Disobeying The Rule Of The Father In Buried Child English Literature Essay

Disobeying The Rule Of The Father In Buried Child English literature EssayThe time of Sophocles dramatizing Oedipus and Antig wholeness has passed and a great many changes has happened to the stage, but since thither be things that have no end with the passage of time we still plunder find traces of myths in our modern drama that are beautifully adapted to our modern era. Sam Shepards family play Buried Child depicts a retelling of many fab stories from the myth of Oedipus to the Egyptian myth of Osiris. In this essay a mythic light is shed on the stage of Shepards masterpiece.The rules of the family structure are shattered and disquieted down, especially this is portrayed through the mother-and-son coupling. As Claude Lvi-Strauss work forcetions the incest taboo is a way of obtaining a wife from some man bug outside his own contagious line. Something that Tilden is unwilling to do, and because of that he returns to his family home. When Dodge says he is too old to live with h is parents, Tilden replies I didnt know where else to go. Levi-Strauss believes marriage is a relationship between two no-relative men to exchange women, something that Tilden has d one with his father, the exchanged woman being Halie. So same(p) a unpollutedal play the structures have been destroyed and as a case chaos has come.Some critics see the setting of the house as a microcosm of a kingdom. Dodge has become a parody of the patriarch, with his baseball cap crown, waiting room throne, and blanket mantle, over which the younger generations fight. His sons battle weakly, having lost their promise and seeming almost as debilitated as their father. (161) in this kingdom of men, all are struggling for dominating the sofa, i.e. Dodges authority. His place on the sofa represents the patriarchy or Jacques La shags Father. He tries to keep his authority in the family, while his sons especially Bradley fight in order to posses it. Bradley, Dodges next son, tries to dominate his fat her by cutting Dodges hair, but is displaced in turn by Vince, who throws away Bradleys false leg (indicative of Bradleys own impotence) and takes Dodges place on the sofa, which Bradley had tried to inhabit. Each of Bradleys attempts to dominate end in failure with him whimpering for aid. Dodge wills Vince his house, land, and furnishings, disinheriting his own sons in preference for a grandson he hardly knows, and one assumes this can only be a purpose based on spite. (161)Bradleys attempts to own the sofa seems ironic, since it seems that Dodge as a father figure has unsexed his phallic ego and he is just striving in vain to prove his masculinity. We can inter it when Dodge says to Halie You tell Bradley that if he shows up here with those clippers, Ill separate him from manhood This happens when Shelley and then Vince steal away his wooden leg from him. Dodge, as the father of the family is the authoritative power and tries to sustain his power among his issue Tilden has viola ted his rules by sexually substitute the fathers place and Bradley is the one who tries to dismantle the father, (he cuts his hair while he is sleeping with wounding his scalp, and wants to posses his sofa and blanket) but it is Vince who is in obedience of Dodge, and because of that Dodge announces him as his successor.Like the myth of Oedipus this family is cursed with an incestuous secret. Tilden talks about his disappeared cocker. And the audience just near the end of the play discovers that Tildens deficient childs mother has been presumably Haliewe were a well-established family once. Well-established. All the boys were grown. The farm was producing enough milk to fill Lake Michigan twice over. Me and Halie here were pointed toward what looked like the middle part of our emotional state. Everything was settled with us. All we had to do was ride it out. Then Halie got pregnant again. Out the middle of nowhere, she got pregnant. We werent playing on havin any more boys. We h ad enough boys already. In fact, we hadnt been sleepin in the equivalent bed for about sextuplet years. (109)The image of their golden years of the past, a well-established family having a productive, fruitful farm is in contrast with the present situation of the family whose lands had not produced crops anymore. That is what happened in the myth of Oedipus whom after killing his father, marrying his mother, Jocasta, and becoming the king of Thebes, is confronted by a plague of infertility that strikes the city of Thebes crops no longer grow to harvest-festival and women do not bear children.Instead of hanging herself like Jocasta, Halie tries to keep the incestuous sin hidden she spends most of her time upstairs looking at the family albums and pictures, representing that she is reluctant to realize the present reality, and instead keeps locking herself in the nostalgia of well-established past memories. While Dodge is talking about this secret, Halie claims to go upstairs, but Dodge boodle her Where are you going? Upstairs? Youll just be listenin to it upstairs You go outside, youll be listenin to it outside.Contrary to Halie, Dodge never goes upstairs or even outside, and he even prevents Tilden to go outside too. Upstairs and the family pictures symbolize Dodges consciousness and his conscience, since he is the one that drowned the child. His disinclination to talk about the past is pictured when e.g. Shelley inquires about the baby in the pictures, Dodge refuses to answer, and even in his habit of watching TV instead of facing people and talking to them. Also Dodges drinking is a classic reaction to guilt, as a person attempts to obliterate the memory of his or her past with alcohol. (Abboston 161)As Susan Abboston writes There is an implication that the child may have been the yield of an incestuous relationship between Ansel and Halie, who seems to have idolized her youngest son. She fondly recalls how he kissed her, and how she was devastated by h is marriage to another, after which he soon died. It is more likely, however, that the father was Tilden, who was so solicitous of the child while it lived, and talks of having lost a son. (Abboston 161) Talking about his son, Tilden uses a plural pronoun We had a baby. Little baby. Could pick it up with one hand. Put it in the other. So small that nobody could find it. Just disappeared. We had no service. No hymn. Nobody came. On the part of Ansel, some critics doubt his earthly concern thinking he may be Halies creation to help her deal with all that has happened. If we take Tilden as an Oedipal character he does not end like Oedipus, but if according to other critics we take Ansel, the youngest son of Dodge and Halie as the childs father, we see that he has already been sacrificed as he has died in a motel room.not only is the child conceal, but also all the characters try to bury themselves too.This family constantly argues over minor things to avoid having to face their own f ailures and complicities. The number of time characters cover themselves or each other with blankets, coats, or corn husks symbolizes the extent to which all are complicit in hiding from the truth, and each other. This is a family so buried in guilt they have lost the power to communicate even on a daily basis. (Abboston 163) Dodge and Bradley try to cover themselves under the blanket, Tilden hides open air among the crops and Halie is hidden upstairs, Things keep happening while youre upstairs, ya know. The world doesnt stop just because youre upstairs. Corn keeps growing. Rain keeps raining.There are many hints that the house is the world of the dead. At the beginning of the play Dodge asks Halie Are we still in the land of the living?(13) Even Dodge considers himself dead when he talks about Halie as Theres life in the old girl yet Vince gets aware of this world of the dead, and decides to stay in his grandfathers house to renew it. His return to the house after six years also s hows the importance of family as peoples root. He realizes that he is connected to this family, that his identity is intricately bound to the bones of this family, notably the male bones. (Hall 102) his looking in the mirror also reminds us of Lacans mirror stage, since he recognizes he is in need of this family in order to have an identity.While looking in the mirror, Vince has discovered an even better device with which to gain a sense of self, complete, whole, and historical through the patriarchal line. The dissolution at the end, however, presents a threat, and it brings Vince back to his home and informs his decision to remain he will stop the dissolution by taking Dodges place, by making the choice that will perpetuate the patriarchy. He has discovered his manlike mission. (Hall 102)In act three, we see bright sun and no sound of rain the suns uncovering from the clouds foregrounds the baby sons uncovering from the earth. Tildens earlier entrances with crops reflect on his utmost entrance with the corpse all connect to suggest fertility and progress. Darkness and rain are replaced by bright sun the rain, having created new growth, suggests that death can be replaced by new life. (Abboston 163) and this is an echo of the myth of Osiris. In the myth of Osiris, often linked to the ritualized death of the corn king, the king dies to return the land to life with his sacrifice-so Dodge, the family patriarch, dies, and the new blood, Vince, inherits the land. (Abboston 164) So that like a Dionysus myth we see death and mingle together, by Dodges death and Vinces authority we confront a restoration, regeneration and renewal.The sun, which has brought out the crops, is echoed by the son Tilden carries in his arms at the close. If the buried child has been the source of the family curse, then its exhumation may signify the end of that curse and an gratification of the sins of the previous generation. The dead son whom the family has avoided and denied has been brought to light and faced, and the murderer, Dodge, has died, allowing the living son, Vince, to take charge with a clean slate. (164)

Organization Culture In Multinational Companies Management Essay

Organization Culture In Multinational Companies Management striveMultinational companies argon facing more challenges when they judge to develop a cohesive organizational culture than domestic companies. In this subject argona, several cases experienced from genuinely flavour examples pass on be presented. They will be discussed with theoretical framework which allows reader to understand each situation through comparative analysis. The theory of pagan Management, Cross Cultural Communication Negotiation, Leadership, Motivating race is selected for cross referencing in accordance to the topic of the study.The study focus on two main partPart 1 Describe the challenges faced by MNCs on developing a global management, moving forward to identify the key challengesPart 2 Focus on managing people across borders and cultures implementing Cultural Management concepts and theories (Hofstedes Cultural Dimensions 1980), leadership Motivating theories. The intention of this part is t o give a critically word on real business situations while being aware of the application of these selected theories.The findings of useful methods for global leaders developing organizational culture will be explained in the conclusion. I will give my personal reflections on how the application of these theories will benefit leaders working in the similar situations in the global business.Part 1 Challenges on developing a global managementOrganizations are always facing challenges when they are doing business globally. These challenges include the assessment of the environment, managing societal responsibility and ethics, communication negotiation across cultures, etcetera In the following paragraphs, I will give journal articles related to a real life example that has faced several critical challenges when developing a global management.On 5th March 2012, China Labour bulletin reported a string of press release that there are a total of 27 logged reports of strike and protest from workers across China with the majority group of workers from the industrial/manufacturing and transport sector. The strikes and protests are mainly concerned on low wages, reduction of annual bonus, unreasonable employee layoff, management takeovers and relocations.A related such case is workers at Putzmeister Machinery in Shanghai stages a strike over the unsatisfactory compensation package being offered after the fraternity takeover by SANY Group. Putzmeister Machinery being ace of the largest German Manufacturer of concrete pumps has been acquired by Sany Group (one of the largest manufacturer of heavy machinery in China). Workers who are benefitting from the existing European management system and packages stinkpotnot accept the emergent implementation changes adapted from the Chinese company. It is believed that SANY has amended the package not in favour to the workers.After acquisition took place, employees who are not from SANY Group are touch by several changed fa ctors both internal and external of the SANYs company policy. The culture which forms the organizational environment requires managers improve their cross-border learning capabilities. Managers from parent-country nationals or host-country nationals cannot ignore local employees makes. favored leader manager advocate to earn peoples loyalty and trust by learning their different cultures, they also try to help employees to understand what their future and opportunities may have in place.Besides, exercising effective Change Management is necessary for leaders to understand the culture changes. This is because culture does not simply mean intellectual who talks with whom, about what, and how the communication proceeds, it means how people encode messages, the meanings they have for messages, and the conditions and circumstances under which various messages may or may not be sent, noticed or interpreted. (Samovar and Porter, 1997) In this regards, the needs to understand the cultur al variables are also necessary for Managers of SANY Group to enquire the skill to avoid miscommunication.According to the study from Cameron and Green (2004), the role of a leader in acquisitions is providing situations to the individuals in organization as follows11. Ensure that the team knows that a change will happen and things will not be the same way they used to.2. Ensure that the people understand the things that will change, what will stay the same and when will all this happen.3. bring forward people try to do things in a new way and provide the right environment.Part 2 Managing and actuate people across cultures state from the same culture usually share a common general understanding of right and wrong, acceptable fashion and inappropriate behavior. In multinational companies, staffs are from a variety of national cultures, they have variety cultural backgrounds, this requires managers who are operating in global interdependent market operating in a series of hugely di verse landscapes (Tom Keen, Jim Leadership Landscapes, palgrave, 2007). Serious misunderstandings may happen when managers cannot understand staffs real needs, values and self-actualization. Managing and motivating people across culture are not only a challenge to large companies but also something applicable to small-scale companies while multinational people are collected together.A reference of a real life example of China riches center field East Machinery which is doing heavy machinery leasing business located in Dubai.China wealth Machinery Co Ltd is a subsidiary of SANY Group which was founded in 1999. The main core of business is leasing heavy equipment to civil and building contractors. Based in Hong Kong, China Wealth set up a subsidiary branch in Dubai on 2008, which is China Wealth Middle East Machinery (L.L.C) .In China Wealth Middle East Machinery, there are workers from four different countries, China, Bangladesh, Pakistan and Afghanistan. These workers are employe d in various operating position like operators, maintenance engineers, foreman and P.R.O. The company has faced challenge in managing, motivating people from different culture. In a general perspective, there is a similar culture with very some differences among the employees from Bangladesh, Pakistan and Afghanistan. However, the difference can be substantial when they are compared with the Chinese culture. Hofstedes study gives comparison amid Chinese and Bangladeshi cultures, the results are illustrated as follows,KeyPDI advocate DistanceIDV Individualism vs. CollectivismMAS Masculinity vs. FemininityUAI Uncertainty AvoidanceLTO Long landmark orientationLOTLTO Long term/Short term orientationFigure Comparing China and BangladeshThe chart in Figure 1 shows the comparison of PDI, IDV, MAS, UAI between Chinese and Bangladeshi culture. There is significant resemblance between the two cultures in PDI, IDV and MAS where PDI and IDV are exactly the same. In contrast, the great diff erences between the two cultures come at UAI and LTO.There is distinctive evidence in the relationship among Chinese and Bangladeshi. They have both displayed high power distance in their workplace. Chinese have given more extol for the elderly it is believed their behavior assembled from the Chinese Confucianism when taught in the younger days during their upbringing. Whereas, even the junior will to embrace with outstanding achievement, they are not able to gain the same respect as the elders. In China Wealth company, all the Bangladeshi operators are younger than the Chinese operators, therefore, they will only take the role as helpers at the beginning even the Bangladeshi has accumulated enough or already have experience. In addition, the Chinese will always command a overnight term orientation and a better salary package which is almost double when they are both put on the same position. It can be seen as unfair but is widely accepted in the company.Furthermore, Bangladeshi w orkers show their high uncertainty avoidance which can be explained that they do not mind the condition and acceptance of lower responsibility in exchange for a secured salary. They are easily contented people who do not longing a long term orientation. They can generally accept Salary which is sufficient to cover the basis expenses and support the family back home. On the contrary, Chinese workers need high salary and seek for long term orientation which allow them to spend freely and opportunity for promotion in future. They are risk taker and are ready for any unforeseen event that may or may not occur, they can also take challenges at work.Thus, managers who work as multicultural role on motivation and management blend in different ways. They must consider the entire national and cultural context on a situation-by-situation basis, settle reward system not only rely on money but also search for their interest and satisfaction, means of keeping occupied, status and prestige. It is difficult to judge which type of workers behavior in China Wealth company is right or wrong. Managers should make different job motivation between Bangladeshi workers and Chinese workers according to their different cultures.Part 3 ConclusionsIn globalization competitive environment, leaders can be expatriates. They need to have eight-fold competencies to deal with challenges like cross border transaction. I think it is important for them to create new culture initiatives by allowing employees to extent their thinking and actions. Creativity can be one of the useful methods when dealing with multiple challenges. Creativity means doing things from a different way, leaders must learn different culture from people outside the system.Leaders should consider the cultural differences when creating a new culture for the merger or acquisition.( Kuada, 2008), they can enable reward systems, planning and performance management, motivating systems working together to support the objective and preferred behaviour.The leaders job comprises cultural adaptability, leadership experience and technical knowledge, level of authority and autonomy etc. No single leadership style works well in all situations.( Helen Deresky, 2012) Global leaders should broaden their horizons strategically and cross-culturally. Besides, leaders should also try to develop a flexible model what can adapt to local situations then apply around the world.

Anysys Fluent Simulation Of Turbulent Flow Engineering Essay

Anysys Fluent Simulation Of Turbulent Flow Engineering EssayThe characteristics of silver coalesce with fulminant expansion in a 12 diameter ratio pipe are investigated using ANSYS Fluent. Results show fluid re-circulates just after expansion, distance of recirculation zone approximates to 0.35m. Velocity, turbulence intensity and pressure substitute along pipe length in accordance with Bernoullis principle. Influence of change in turbulence dumbfounds on accuracy is overly investigated with the Reynolds Stress object lesson providing the comparatively best fit although other turbulence regulates (realizable k- and SST k-) provide reasonably close fitting imitates. Results were checked for mesh independence and validated.Computational Fluid dynamics (CFD) involves computational simulation of fluid scarpers in different situations employing numerical solution of basic flow compares e.g. the continuity equation and other equations over a discretized unit fictitious charact er (Versteeg, and Malalasekera, 2007). The usage of CFD transcends the traditional scope of chemical engineering profession into wider areas such as oceanography, biomedical engineering electrical circuitry, etc (Fairweather, 2011). fulminant expansion in pipes involves fluid flow from a smaller hydraulic diameter to a larger one. Flow separation usually occurs in a sudden expansion scenario, where a part of the fluid flows in opposition to the main fluid flow. This are called eddies, and are strong contributors to the irreversibility of practical flows as energy is dissipated by this eddies. therefore it is of great signifi thronece to be able to mildew eddies in a sudden expansion flow adequately and observe the characteristics of this recirculation zone (efluids, 2011 Gharegbagi and Ali, 2011 Mahmud, 2011 Roy, et al 2010).Sudden expansion is a simple looking but intriguing case of fluid flow in pipes. Sanmiguel-Rojas (2010) implies that not many signifi sternt studies have bee n make on instabilities encountered in steady, turbulent, sudden expansion fluid flow with respect to spatial structure of piping with D2/D1 = 2. However, previous remarkable work in this subject includes Roy, et al (2010) and Mansoori and Bazargan-Lari (2007).Examples of scenarios in which the above phenomenon occurs include Flows into a tank, oil drilling and extraction, plug flow reactors, combustion engines, aerodynamics, etc.SoftwareANSYS Fluent is a commercial message CFD package that models flow via the finite- tawdriness method (a variation of the finite inequality method) created by the company Fluent (now part of ANSYS Inc.). Pre-processing of the case study (meshing) was done on ploy which comes along with Fluent (now ICEM). The version of Fluent employed in this report is 12.1 (CFD-online, 2011 Weidner, 2011 ANSYS, 2009).This report covers the Reynolds Average Navier-Stokes (RANS) modelling of turbulent flow with sudden expansion in a 1 2 diameter piping, using the pressure based solver and the second order upwind difference scheme in ANSYS Fluent. effect of changes in turbulence models on computational time, and accuracy would be examined, visual plots would be used to describe and analyse modelling results.SIMULATION METHODOLOGY soma 1 diagrammatic representation of simulation process (Fairweather, 2011)Nature of Fluid flow downstairs considerationCalculating the Reynolds number of the flow helps to determine the temperament of the flow. At Normal Temperature and pressure (P = 101.325 kgm-2, T = 288.16 K)Generally it is accepted that flows with a Reynolds number (Re) 4000 are turbulent in nature. Therefore it is established that the flow under consideration is a turbulent flowReynolds-Averaged Navier Stokes (RANS)RANS involves the time averaging of the equations that govern turbulent fluid flow to capture information on variations that occur on a minute scale while avoiding horrendously lengthy computation times. RANS represents variatio ns as a mean such that and PRANS is employed in obtaining the equations that were numerically solved in this report assuming constant velocity and viscous flows (Fairweather, 2011).GeometryThe geometry consists of two pipes of diameter ratio 12 joined together through which fluid flows with no bends as shown belownumber 2 geometry of pipe showing mesh grid/mesh discretizationGoverning EquationsContinuity equationMomentum equation (x-direction only)Where TURBULENCE MODELSRealizable k- modelThe k- model is a two equation model that assumes a linear relationship between Reynolds stress and esteem of strain. It has the advantages of steadfast computation time, wide usage and extensive validation. However, it predicts badly the length of eddies for complex flows. The realizable k- model is an update to the model based on observed strengths and weaknesses of the measure k- model (Fairweather, 2011 ANSYS, 2009).Below is a mathematical representation of the standard k- modelWhere = k or S=source term for k or Sk= G- (production rate of k-destruction rate of k) S= (C1G-C2)(/k) = (production rate of k-destruction rate of k)N.B. for this simulation andSST k- modelThe k- model is also a two equation model based on the Wilcox k- model. It is sufficient for wall bounded flows and free shear flows as it performs low Reynolds number corrections, computation time is relatively fast and accuracy is better than the k- model in most cases. is specific dissipation rate and is analogous to a ratio of /k. The SST k- model is an improved version of the standard k- model (ANYSYS, 2009).Reynolds Stress ModelThis is a very rigorous model, with seven equations unlike the preceding 2-equation models. It provides more accuracy where other models are faulty e.g. impinging flows and can predict fluid flow for a lot of cases closely without any dedicated / individual adjustments. However, computing equals are large (Fairweather, 2011)The first six equations of the RSM model can be condensed into the equation belowWhere The seventh equation (turbulence dissipation rate) isN.B. in this simulation andNumerical methodsThe discretization employed is the finite glitz method. It is a variant of the finite difference method. This scheme splits up the domain into discrete control volumes over which the control equations are resolved using a truncated Taylor series expansion. Finite volume method is the most established of Discretization schemes in CFD modelling. Convective fluxes were evaluated with the second order upwind-difference scheme (Fairweather, 2011 Versteeg, and Malalasekera, 2007).Boundary conditionsTable 1 edge conditions for numeric solution (adapted from Versteeg, and Malalasekera, 2007)Realizable k- modelSST k- modelReynold Stress modelInletk = 0.01148438 m2s-2 = 0.02888982 m2s-3k = 0.1148438 m2s-2= 27.95085Rij = =OutletInteriork = 0 = 0k = 0 = 0Rij = 0 = 0Wallslaw of the wallLaw of the wallWall functionsConvergence criteria and levelsFor all the equations solved by each model, a uniform convergence amount of 1.0 x 10-4 was used for every equation solved. The value stand for an informed compromise between acceptable accuracy and realistic computation time (ANYSYS, 2009). It is beseeming of note that for the RSM model, this relatively stringent criterion caused the number of iterations to exceed 14,000 without any obvious improvement in results as shown in fig 2. Therefore a cap of 4,000 iterations was placed on the RSM calculations. Results show there was no ensuing negative impact on accuracy of numerical solution. build 3 loop-the-loop length for RSM model showing mesh topology Independence testThe table below shows that results from the modelling experiment are similar and essentially the same inside three (3) decimal places of precision irrespective of mesh size employed. Also since assurance of mesh independence cannot be guaranteed by mere reduction in cell size (Sloan et al, 1986), an attempt was made at adaptive meshing to attenuate important flow variations and phenomenon with the same results obtained.Table 2 Grid/Mesh independence of simulationGambit Mesh/Grid sizeVolume of unit cellsMass flow rate at inlet kgs-1Mass flow rate at Pressure-outlet kgs-1ErrorPercentageDifference (%)5439,9930.0168099440.016809996-5.22E-083.09 x 10-47163,3110.016784670.0167845511.19E-077.08 x 10-41055,1820.0167289940.0167292042.1E-071.255 x 10-310b100,6930.0167289940.016728895-9.9E-085.9 x 10-41516,7500.0166090190.016608695-3.24E-071.95 x 10-3N.B. 10 b means mesh size 10 with boundary floor mesh added (adaptive meshing)Grid optimization (Mesh finesse Vs Time trade off)The greater the volume of unit cells in grid per geometry, the better the accuracy of numeric analysis. However, within the scope of grid independence, results are relatively uniform irrespective of mesh size. The cost of finesse of grid is computation time could be noticed with the case of mesh size 5 (439,993 cells) which took almost forever to compute using the RSM model and had to be terminated. Thus mesh 10 (55,182 cells) and 10b (100,693 cells) were employed for analysis with other mesh sizes serving as validation checksRESULTS AND ANALYSIS articulation 1 winning a close look at flow close to the walls of the pipe, we see the effect of sudden expansion resulting in backflow of fluid creating velocities in the opponent direction (red box). Recirculation zone is virtually 0.37m in length. We also can see how the fluid adjust to changes in geometry with a sharp rise velocity to look at the voids created by liquid moving backwards then a dilatory decrease as pressure pile us towards the exit of the pipe physical body 4 velocity variation along length of pipe close to the walls showing effects of recirculationFig 6 shows the variation in turbulence intensity. It can be seen that the flow becomes more turbulent around the recirculation zone with dead (stagnant) flow occurring just at the corners of the pipe. Fig 7 displays the total pressure variations in the pipe. It can be noted that sudden expansion causes a drop in total fluid pressure. Fig 8 shows the radial-ply tire velocity and profile. It can be noted that velocity variation in the radial direction is minimal, which is typical of plug fluid flow depicted by fig 5. Fig 9 is a streamline plot of axial velocity, velocity variation along the axial direction is more dominant than in the radial direction, also worthy of note is the length of the recirculation zone (black box) and the reattachment zone.Fig 5 stages of flow development at different positions on pipe lengthFig 6 Turbulence intensity profile of fluid along length of pipeFig 7 Total pressure profile of fluid along length of pipeFig 8 Radial velocity profile of fluidFig 9 streamline plot of axial velocity of fluidPart 2Fig10(a-c) shows axial velocity profiles for different turbulent models in order of increasing complexity (realizable k- SST k- RSM). Curves get smother s howing a more gradual response of the fluid to changes and also approach exact solution, as model complexity extends. However, all the essential features of the fluid flow are well represented by all models.Fig 11(a-c) displays turbulence intensity variations, more variation details are captured as model increases in complexity. Worthy of note is that the SST k- model provides a more detailed picture of turbulent intensity variation in reference to the other models picking up intensities as low as 5.42 x 10-5 %, while the realizable k- picks up a minimum of 0.336% and RSM 1.45%Fig 12(a-c) shows streamline plot of axial velocity, though length of recirculation zone remains approximately the same the representation of velocity magnitude in recirculation zone varies visibly for each model.Fig 13(a-c) is the radial velocity profile the SST model indicates larger radial velocities along pipe length than both than both the realizable k- and the RSM models. For all models radial velocity variation is dominated by axial velocity variationsFig 10a k- modelFig 10b SST modelFig 10c RSM modelFig 11a k- modelFig 11c RSM modelFig 11b SST modelFig 12a k- modelFig 12b SST modelFig 12c RSM modelFig 13a k- modelFig 13b SST modelFig 13c RSM modelVALIDATION OF RESULTSFor CFD, convergence of numerical iterations does not really count for such(prenominal) as Versteeg and Malalasekra (2007) put it results are at best as good as the physics embodied in it, or at worst as good as the skill of the operator. Thus, validation of results becomes extremely important. The results obtained herein would be validated thusBernoullis equationFor an ideal fluid flow Bernoullis equation enables us to calculate the velocity at any point in the pipe (assuming constant flow rate, and negligible friction losses). Therefore we can validate produce velocity from fluent using this principle (Roymech, 2011).Where vin = 1.73855 ms-1, P1= 101.325 kgm-2, P2= 101.325 kgm-2, g = 9.81 ms-2 =1.225 kgm-3 z1 = 0.1m z2 = 0.1mThereforeMass flux variation results from FluentThe third mechanism for validation will be the CFD package fluent itself. Analysis of the computation results as presented in table 4.0, show that value of errors resulting residuals is very low (less than 0.0095%) indicating conservation of mass during numerical calculations which add credit to suitability and accuracy of model.Table 3 comparison of percentage error of each modelMODEL/mesh volumeK-EPSILON (%)SST K-OMEGA (%)REYNOLD STRESS (%)50.0003090.00352N/A70.0007080.0044683630.000673233100.0012550.0078670.00112410 b0.0001530.002580.001488150.001950.0007830.00927N.B. 10 b means mesh size 10 with boundary layer mesh addedResearch journalsIn addition to the above validation processes, the results of modelling experiment reported in this work were compared with previous research works such as (Roy, et al 2010), (Mansoori and Bazargan-Lai 2007) and (Teyssandiert, 1973). Results obtained corroborated foregoing analysis a nd results obtained it the above mentioned papers.CONCLUSIONIn summary, CFD modelling of sudden expansion flow in a 12 diameter ratio piping posses the following characteristics.Sudden expansion in pipe flow results in local pressure lossesFlow amply develops into plug flow before exit at outlet and majority of the variations occur axially along reactor lengthRecirculation of fluid occurs after sudden expansion for a lengthspan of approximately 0.35m along pipeViscous effects along wall boundaries help dissipate energy of turbulent eddiesThe realizable k- model predicts the size and strength of recirculation zone poorly, but as flow develops into plug flow, the models accuracy remarkably improves with reference to the other models tested.Turbulence models become better with increase in complexity of model from k- to SST k- to RSM. Ability of other models to better the k- model in recirculation zone prediction can be attributed to embedded corrections for boundary layer flow, turbul ent kinetic energy and dissipation rates.

Literary Essay on “in the Kitchen” by Henry Louis Gates, “Am I Blue” by

The meaning of segregation is a disliking matter, all African Americans wanted was equal rights, no harm against them, and to be seen as one. Yet, the African race had to endure on changing their appearance, being compared to animals, and having to alter public space just to try and conk in with the white community. Hearing stories of those such as Henry Louis provide and Brent Staples shows us how history can repeat slightly from the past. Indeed, African Americans would try and transform their hair, going from kinky to strait. In Henry Louis Gates, an American Literary critic, short story In the Kitchen (1994), informs the reader the politics of good hair which is straight and bad hair which is kinky (314), The name In the Kitchen is ambiguous meaning it has a double meaning. One meaning it is being in a three dimensional room, and the other meaning doing hair. Gates uses process analysis to give reader a vivid picture on how the African Americans endure on the difficult process of straightening their kinks, just to fit in with the white society. Given details on how African Americans would change their appearance just to try fit in with the white culture. According to Alice walker, she gives examples on how no matter what African Americans do to change their appearance as far as hair, African Americans will still be compared and objectified to animals. Laster 2Additionally, In Alice Walker, an American Author, short story Am I Blue she persuades the reader to be sympathetic to animals and to show how similar animals and humans are. Alice Walker also gives examples on how sl... ... In conclusion, segregation is how separation was between groups of race is a dreadful situation. African Americans wanted no harm, they wanted be able to share the analogous places such as restrooms. The black community tried to change the way they looked, sound, or objectify to animals. African Americans are being seen as a prejudicial light, because of the skin color, hair, and where we come from.

Review of Dickersons End Of Blackness Essay example -- essays research

Debra Dickerson, a lawyer and journalist, sets out to inform blacks that they have to give up on the past. If they do not give up on the past, there will be no future for blacks in America. She opens her oblige, The End of Blackness Returning the Souls of Black Folks to Their Rightful Owners, by saying this book will both prove and promote the idea that the concept of blackness, as it has come to be understood, is rapidly losing its ability to describe, let alone predict or manipulate, the political and social behavior of African Americans (p.3). My first thought after finishing this book was that she did not prove anything.Dickersons goal in this book, I gather, is to criticize contemporary approaches to race. She does this without leaving anything or anyone untouched. She questions the civil rights establishment, which sets the current tone of black politics to white apologists who continue to minimize the affects of slavery. One of her main arguments is that as long as blacks de fine themselves in terms of inherited blackness the civil rights movement will never be complete. Not only do blacks need to stop identifying with the past, they must surrender. According to Dickerson, blacks must consciously give up on achieving racial justice (p 16), is this a possibility?I do give credit to Dickerson for noting that blacks in America still face structural barriers to equality, among them poor scholastic achievement, crime, family breakdown and infant mortality however, ...
