Asian and American Women in the Media free essay sample

Compares how the American media portrays female Asian athletes and female American athletes. This paper compares and contrasts Asian women in professional and competitive sports against American women that are engaged in the same sports. The author emphasizes the role of Chinese and American women in the Olympic games. He then demonstrates how the popular media in the United States tends to present female Asian athletes as being overly dedicated to their respective sports to the end goal of drug use or cheating, while female American athletes are presented as being dedicated but also are completely honest in all respects. The American and the Asian medias treat their own female athletes much as they would their male athletes, but it is evident that the American mainstream media tends to portray Asian women as athletes that are not really competitors but are instead almost monstrous. In articles from the 1998 Summer Games, for example, the allegations that the Chinese athletes were using drugs allowed the media to vilify these women.

Narcissistic personality disorder Research Paper - 1

Narcissistic personality disorder - Research Paper Example All of these symptoms characterize an individual with poor social interactivity and will likely manifest opportunistic personality traits in the pursuit of exploiting others in their social and professional environments. The narcissist’s lack of empathy creates distance between himself and others in a variety of social and professional environments when disregard for the well-being of others becomes an ongoing, blatant display of self-importance. When confronted by others about these behaviors, an individual with this disorder should be expected to be defensive and manifest behaviors typical with a person who has experienced radical blows to their self-esteem. The narcissist may become disruptive and begin a process of attempting to denigrate the confronter either publicly or privately in an effort to restore their own reputation, an attitude common with individuals who maintain absolutely false perceptions of reality. ... n, this characterizes an individual with unhealthy relationship focus who will likely superimpose false self-confidence over what is actually low self-esteem that continues to place the narcissist amid a distorted reality that leads to unsatisfying relationships and extreme grandiosity that can produce antagonistic responses from others they encounter in their social environment. The triggers of narcissistic personality do not seem to be universally defined, however some of these attitudes of self-importance are developed earlier in adolescence during the period of cognitive development where the individual is experiencing identity formation, influenced by parental involvement or the quality of adolescent relationships during these formative years. However, there is also evidence that environmental triggers also lead to the development of narcissistic personality disorder that occur later in adult life. As one relevant example of adult onset narcissistic personality disorder, conside r a high-performing salesperson who rises to authority quickly and is especially talented in a specific creative field. Constant attention and endorsement from superiors can lead an individual to experience sensations of invincibility that impact the quality of relationships with coworkers and senior-level management. An individual fitting this classification may abuse their expense accounts, degrade associates, and begins to lose personal understanding of how this behavior disturbs the quality of relationships in the professional environment (McDonald, 88). In this lifestyle scenario, the trigger of narcissistic personality disorder is constant reassurance from important colleagues or superiors that the individual is successful and provides extreme value to the organization for their

Achieving the NAEYC Standards Essay Example | Topics and Well Written Essays - 1500 words

Achieving the NAEYC Standards - Essay Example I met this standard. I got to understand what young children are like; understood what influences their development; and used this understanding to create great environments where all children can thrive. During my internship, I took part in various voluntary activities whereby I engaged personally with individual children. For instance, in the first day I hold a child who is five months, and he was crying; I sat with him and played with him by using different toys, and I used a toy to teach him the colors (red, green, yellow, and blue.) The first couple of weeks was very informative and built block throughout the entire internship; I observed a lot. It is important for any professional teacher to get to know and develop an understanding of children in their classroom. These observations helped me get a deeper view of the thinking and reasoning skills these children possessed. Hence, it gave me an easier time creating any game that would point them in the right direction such as I ma de a traffic light which helped them to understand what they saw every day on the street when they came to the school. I put it in the outdoor play and, I explained that red means stop, yellow means slow down, and green means go. Then, they pretended that they were the policemen who controlled the traffic. They were very active and happy, and they loved it. Thus, through the sensitive nature the simple it was to meet their learning needs and develop a productive and comfy environment for teaching and learning.

The Labor Market Discrimination Essay Example | Topics and Well Written Essays - 1250 words - 2

The Labor Market Discrimination - Essay Example Also, the reduction of the discrimination from the beginning like in schools and the removal of complete disparity at this stage helps in developing more diverse society and a more effective labor market as well. The focus on skills rather than the creed and culture is also a major factor impacting the reduction of the Labor Market Discrimination. Other factors that also impact the Labor Market Discrimination include the opening up of fewer jobs for people and the acceptance of genders, castes and creed helps in improving the condition of the Labor Market Discrimination. The three movies that have been discussed in this class include Freedom Writers, Rossie the Riveter and Crash. The three movies although are of different genres and come from completely different views and insights have the main theme of gender and race discrimination. For instance, the movie Crash is based on a complete racial discrimination where the police officer is against African Americans and hence takes the step of even sexually abusing here in a routine stop. All actions that the police officer takes are based on complete racial discrimination and have a major impact on the story as a whole. In terms of Rossie the Riveter, it is clear that the discrimination is mostly based on the women and how women are treated like they cannot work. In the normal world, there are a number of jobs that are believed to be a ‘man’s job’ and women are considered to be unworthy of doing the job. This story has brought out how women overcome all the conventional beliefs and s how the world that they can work together and can work as well or in fact better than men in a number of occasions as well. Considering the Freedom Writer the story brings out how a culturally mixed class work together and how a woman is able to bring an unruly class to a more organized and well-behaved class.  Ã‚  

Reynolds Averaged Navier Stokes (RANS)

Reynolds Averaged Navier Stokes (RANS) V1.5 Equation for ns changed(Removed time) Changes are bolded Before Computational Fluid Dynamics(CFD) was developed, theoretical studies on high swirling confined turbulent flows can only be validated by conducting experimental studies. These experimental studies require long leading time and high cost. Now, with the help of CFD, researchers are able to study these complex flows in a much shorter time and with a lower cost incurred. Many experimental studies have been conducted on the high swirling confined turbulent flows but little has been done on the computational modelling. Most of these intricate flow simulations are accomplished at the expense of high computational cost methods such as Large Eddy Simulations(LES) and Direct Numerical Simulations(DNS). Thus, a lower computational cost alternative will be very helpful in the studies of high swirling confined turbulent flows. Thus, this project will be using the Reynolds Averaged Navier Stokes (RANS) based turbulence models in ANSYS FLUENT to simulate the high swirling confined turbulent flows in two different test cases and the results validated with experimental data. The aims and objectives are discussed as follows: Aims and Objectives Aims To validate the accuracy of RANS based turbulence models for the simulation of high swirling confined turbulent flows. Objectives To simulate the high swirling confined turbulent flows using ANSYS FLUENT with different RANS turbulence models. To compare the numerical data from the simulations with the experimental data to validate the accuracy of the turbulence models. To understand the effect of the RANS turbulence models on the predicted results. Review of Confined Swirling Flows Confined swirling flow plays an important role in various engineering fields. For example, they can enhance the mixing process in the stirred tanks, improve the separation of particles in cyclones [1] and also increases the flame stability in gas turbine combustors. So, what is a swirling flow? A swirling flow is a flow where a swirl velocity that exists in the tangential direction other than the flow motion in the axial and radial directions. The swirl velocity of the flow plays a major role in the evolution and decay process of swirling flow motion but not the radial velocity of the flow as shown in a study by Beaubert et al. [2] A swirling flow consist of two types of rotational motion. A solid body rotation at the inner region near the centerline and a free vortex motion at the outer region. [14] Solid body rotation and free vortex motion respectively has its velocity directly and inversely proportional to the radius of the pipe at the centre of their axis of rotation as shown in Figure 1. Figure 1: Velocity profile of swirling flow in a pipe. [4] Confined swirling flow can then be categorized into subcritical and supercritical flows. A subcritical flow has a reverse flow at the exit and is very sensitive towards changes at the exit as shown experimentally by Escudier and Keller[11]. On the other hand, the supercritical flow has no reverse flow at the exit and is insensitive towards variation at the exit.[10] Subcritical flows are formed when the ratio of maximum swirl velocity to the averaged axial velocity exceeds unity was stated in a theory by Squire[12]. Review of Computational Fluid Dynamics(CFD) CFD is a methodology which is employed to study fluid flow using numerical analysis and algorithms to solve the governing flow equations. In the past, the field of fluid dynamics was made up of purely experimental and theoretical studies. CFD is considered the third approach in the studies of fluid mechanics and would complement the two existing methods. [5] The three main elements when implementing CFD are the pre-processor, solver and post-processor. The pre-processors task is to transform the input of a flow problem into a form that is suitable for the solver. During pre-processing, the geometry of the problem is defined and the flow domain is divided into smaller cells (meshing). The physical (eg: turbulence) and chemical phenomena that needs to be modelled are selected and the fluid properties are defined. Next, the boundary conditions are given to cells which interacts with the domain boundary. The solution to the flow problem is stored in the nodes in each cell. In the solver, the conservation equation containing the mass, momentum, energy and species is integrated over each cells. Then, the unknown variables of the equation are interpolated and substituted back into the equation. The solver then runs numerical techniques to solve the derivatives and flux in the cells. Lastly, the post-processor allows user to analyse the data obt ained by plotting graphs and observe the flow animation. [6] Review of Turbulence Flows All fluids in motion are governed by the conservation of mass equation and the Navier-Stokes equation. The latter equation relates the flow properties such as the velocity, pressure, density and temperature for a moving fluid. The conservation of mass equation and the incompressible Navier-Stokes equation (in Cartesian tensor notation) can be respectively written as Turbulence is shown to develop as an instability in the laminar flow through detailed analysis of the solutions for the Navier Stokes equation. [7]. In principle, Direct Numerical Simulation(DNS) can be used to simulate very accurate turbulent flow by solving the exact equations with the appropriate boundary conditions. However, it requires very large amount of computational power as this method has to represent all of the eddies from the smallest scale to the largest scale and the time step chosen must be small enough to resolve the fastest fluctuations. The turbulent eddies will be discussed in more detail in the next section. The two other methods that can be used to simulate the turbulent flows (with decreasing computational power and accuracy) would be the Large Eddy Simulation(LES) and turbulence modelling with Reynolds Averaged Navier Stokes equation (RANS). Basically, LES solves the governing equations partially as only the large eddies are solved using the governing equations and the filtered smaller eddies are modeled while RANS models the entire turbulence eddies and only the mean variables are calculated. For turbulence modelling, the minute details of the turbulent motion are not prioritized so only the average flow properties are solved. In a turbulent flow, the velocity field fluctuates randomly in both space and time. Despite the fluctuations, the time averaged velocity can be determined and the velocity field equation can be written as: () where is the time averaged velocity and is the fluctuating component in the velocity field. Other than the velocity, other flow properties can also be decomposed into its mean and fluctuating parts. In our simulations, the flow is assumed to be steady, have constant density and axially symmetric. Thus, the incompressible Reynolds Averaged Navier-Stokes (RANS) equations (in Cartesian tensor notation) can be written as Where is the Reynolds Stress tensor, which is a component of a symmetric second order tensor from the averaged process. The diagonal terms are normal stresses while the non-diagonal terms are shear stresses. The Reynolds Stress can be understood as the net momentum transfer due to velocity fluctuations. This term also provided unknown terms to be equation and thus, more equations have to be found to match the number of unknowns to solve the equations. A straightforward method of generating equations would be to create new sets of partial differential equations (PDEs) for each term using the original set of Navier-Stokes equation. This can be done by multiplying the incompressible NS equations by the fluctuating property and time averaging them to produce the Reynolds-Stress equation. By deriving the Reynolds Stress term, we can identify what is influencing the stress term but the problem with this approach is that more unknowns and correlations were generated and no new equations are formed to account for these unknowns. [7] Thus, these unknown terms have to be modelled to close the equation before they can be used. Review of Turbulence Eddies The velocity field fluctuations in the turbulence flows are actually the eddies in the flow. The eddies moving pass an object generates the turbulence kinetic energy and the length scale of the eddies, are determined by the diameter of the object. As the large eddy break down into smaller eddies, the turbulence kinetic energy will be passed down and eventually dissipated due to viscous forces in the flow. Thus, according to the Kolmogrov scales, the length and time scale of the smallest eddies depends on the rate they receive energy from the larger eddies, and the kinematic viscosity,. It is also noted that the rate of turbulence energy received is equal to the rate of turbulence energy dissipated so, . The Kolmogrov scales shows the length and time scale of the smallest eddies to be and respectively. [8] These expressions can then be used to determine the length and time scale ratio between the small and large eddies. () () From the equations above, we can conclude that the large eddies are several orders of magnitude larger than the small eddies. Thus, even at a low Reynolds number, the time and length ratio between the small and large eddies are significant enough to affect the number of elements and time step required to model the entire turbulent flow. Therefore, instead of solving all the eddies, turbulence modelling is required to reduce the amount of computational cost of CFD. Summary The understanding of the motions of confined swirling flows and characteristic of the subcritical and supercritical flows will be useful when explaining the simulation results. Before the simulation results are obtained, it is also important to identify the basic steps of running any CFD simulations which are the preprocessing, solving and post processing. DNS solves the exact NS equation while LES solves the equation for larger eddies and models the smaller eddies. The process of solving the exact equations takes up a lot of computational power as it would need to represent the all the turbulent eddies involved and a suitable time step has to be chosen to resolve the fluctuations. When compared to DNS and LES, RANS turbulence modelling requires the least computational power as it does not solve the exact NS equations but instead, models the entire turbulence eddy and only solves the mean average variables. The low computational cost of RANS turbulence modeling is the primary reason why this project has chosen it to simulate the confined swirling flows. However, the accuracy of this methods requires validation, which is the aim of this project. The RANS turbulence models created will be based on the PDEs of the Reynolds stress as a guideline as it shows how the Reynold stress behave. Thus, the next section will elaborate more about the RANS turbulence models that will be implemented in this project. The main objective of the RAN based turbulence models are to model the (Reynolds Stress tensor) and provide closure to the RANS equation. The three main categories of the turbulence models are linear eddy viscosity models, non-linear viscosity models and Reynolds Stress Model(RSM). [9] There are three types of linear eddy viscosity models: algebraic models, one equation models and two equation models. They are based on the Boussinesq hypothesis which models the Reynolds stress tensor to be proportional to the mean rate of strain tensor, by a coefficient named the eddy viscosity,. This infers that the turbulence flow field acts similarly to a laminar flow field. [10] (5) The second term of the right hand side of the equation above is required when solving turbulence models that needs to calculate the turbulent kinetic energy, k from the transport equations. The equation for k is half the trace of the Reynolds Stress tensor. For the algebraic turbulence models, no additional PDE equations are created to describe the transport of the turbulent flux and the solutions are calculated directly from the flow variables. An algebraic relation is used as closure based on the mixing length theory. The mixing length theory states that the eddy viscosity have to vary with the distance from the wall. However, the problem with these equations are that they do not account for the effects of turbulence history. In order to improve the turbulent flow predictions, an additional transport equation for k is solved which will replace the velocity scale and include the effects of turbulence flow history. For one and two-equation models, the modeled k equation is involved thus discussion on the exact k equation will first be done. The exact k equation is a PDE derived by multiplying the incompressible NS equations with , averaging it and multiply with . The exact k PDE equation obtained is The left hand side(LHS) terms are the material derivative of k which gives the rate of change of turbulent kinetic energy. The first term on the right hand side(RHS) is the production term and represents the turbulent kinetic energy that an eddy will gain due to the mean flow strain rate. The second term on the RHS represents the dissipation term which meant the rate at which the kinetic energy of the smallest turbulent eddy being transferred into thermal energy due to the work done by the fluctuating strain rate against the fluctuating viscous stresses. The third term on the RHS is the diffusion term which represents the diffusion of turbulent energy by molecular motion. The last term of the RHS is the pressure-strain term which signifies the tendency to redistribute the kinetic energy in the flow due to the turbulent and pressure fluctuations. In order to close and solve the k equation, the Reynolds Stress, dissipation, diffusion and pressure-strain term has to be specified. For the Reynolds Stress term, it is already mentioned at the beginning that it is based on the Boussinesq hypothesis. The eddy viscosity, is modelled similarly to how it was done for the algebraic models Where is a constant, the length scale of turbulence eddies, is similar the mixing length and velocity scale of the turbulence eddies is replaced by the square root of the turbulence kinetic energy, k. The equation above is an isotropic relation which means that it is assumed that the momentum transport is the same in all direction at any point. Next, the dissipation term is modelled based on the assumption that the rate of turbulence energy received is equal to the rate of turbulence energy dissipated. Thus, we can write the equation and since the equation is homogenous, it can be characterized by the length and velocity scale of turbulence eddies giving Where is a constant. For the diffusion and pressure-strain term, the sum is modelled based on the gradient diffusion transport mechanism as there is the pressure-strain term is small for incompressible flows. The gradient transport mechanism implies that there is a flux of k down the gradient. It is to help ensure that the solutions are smooth and a boundary condition can be applied on k when k is in the boundary. There is no Therefore, the equation shows Where is the turbulent Prandtl number and is normally equal to one. -not completed will talk about the modeled turbulent kinetic energy in one equation spalart allmaras -will talk about dissipation part for 2 equation model in k-e This test case is chosen because the flow was mapped and documented in detail as So et al was able to measure and document the flow in detail using a Laser Doppler Velocimetry(LDV) at 10 axial stations up to 40d downstream. Thus, the validation of the accuracy of the RANS turbulence models on confined high swirling flow can be done. Description of Test Case The flow consists of an annular high swirling stream projected into a pipe of uniform radius, R = 62.5mm with a central non-swirling jet of diameter, d = 8.7mm. The swirl number, S of the flow is calculated with Where U is the axial velocity and W is the swirl velocity. The swirl number just downstream of the swirl generator is approximately 2.25 which indicates that it is a high swirling flow and will cause an adverse pressure gradient at the centreline. The purpose of the non-swirling jet was to delay the occurrence of reverse flow due to the adverse pressure gradient along the centreline from 12d to 40d downstream from the inlet. Geometry (Computational Domain) The confined swirling flow in this case is a subcitical flow according to the rule of thumb of Squire mentioned in Section x. Thus, two different computational domains were used for the simulation of the flow to check if the exit geometry will affect the swirling flow simulated. Figure 2 (temporary figure) The first computational domain is the complete geometry of the pipe which consist of the computational inlet at x/d =1 and the constriction of 0.75R from x/d = 70 to the computational outlet at x/d = 90. The second computational domain is a cut off from the first domain at x/d = 55 where the constriction is removed. Meshing -have not completed it. Will be updated in the next revision. Boundary Conditions Inlet The inlet experimental measurements for the axial and tangential velocity and stresses are provided. However, the radial velocity component was not measured and is set to 0 rad/s. The radial stress is also not measured and was set equal to the tangential stress, whereas the three shear stresses are assumed to be zero. < graphs of prescribed to be added> Outlet Conditions at the outlet are not known prior to solving the flow problem. No conditions are defined at the outflow boundaries as ANSYS FLUENT will extrapolate the required information from the interior. It is assumed that the flow is fully developed at the exit end thus the outflow boundary condition is used. (dphi/dx|exit = 0) Wall The no slip condition is applied.
