Objectives: - To perform a steady-state conjugate heat transfer analysis on a model of a graphics card using appropriate materials for the simulation and properly define the correct solid and fluid zones. - To run the simulation for best possible mesh with combination of coarse and refined mesh in different regions and…

What are some practical CFD models that have been based on the mathematical analysis of Rayleigh Taylor waves? In your own words, explain how these mathematical models have been adapted for CFD calculations. The Rayleigh–Taylor instability, or RT instability (after Lord Rayleigh and G. I. Taylor), is an instability…

Objectives:   Give a brief description of why and where a CHT analysis is used. Maintain the y+ value according to the turbulence model and justify the results. Calculate the wall/surface heat transfer coefficient on the internal solid surface & show the velocity & temperature contours in appropriate areas.…

  Q1. Describe Ahmed's body and its importance.      Ahmed S., (1984) performed a series of wind-tunnel experiments in order to examine the wake structure around typical automobile geometries. The study focused on the time averaged structure obtained from visualizations of flow in the wake region…

AIM Simulate the flow over a cylinder and explain the phenomenon of Karman vortex street.     PART-I Simulate the flow with the steady and unsteady case and calculate the Strouhal Number for Re= 100. PART-II Calculate the coefficient of drag and lift over a cylinder by setting the Reynolds number to 10,100,1000,10000…

AIM: To perform simulation of flow of air through mixing tee at different temperatures and velocities and understand the effect of length of pipe and momentum ratio of velocity for mixing of air by using a short and a long pipe. This is widely used in HVAC applications. OBJECTIVES: Velocity and temperature contour plots…
