Week 2 - Flow over a Cylinder.

Aim: To perform a steady-state conjugate heat transfer analysis on a model of a graphics card for three different velocities 1m/sec,3m/sec and 5m/sec for two different mesh Background theory: With the power consumption of computer graphics cards having increased significantly in recent years, it is now more important than…

  Aim: To Perform the Rayleigh Taylor instability simulation for 2 different mesh sizes with the base mesh being 0.5 mm. Compare the results by showing the animations Rayleigh taylors instability: The Rayleigh–Taylor instability, or RT instability (after Lord Rayleigh and G. I. Taylor), is an instability of an interface between…

Aim: To do a conjugate heat transfer analysis of the exhaust port Why CHT analysis? There are three modes of heat transfer, they are conduction, convection and radiation. Conjugate heat transfer analysis in CFD can combine all these three modes of heat transfer or two. Effectively integrating heat transfer in both fluids…

Aim: To simulate the Ahamed body and to find the coefficient of drag Background theory: The Ahmed body was described originally by S. R. Ahmed in 1984 . Three main features were seen in the wake: 1. The A recirculation region that is formed as the flow separates at the top of the vertical back surface of the model 2. The…

Aim: To Simulate the flow with the steady and unsteady case and calculate the Strouhal Number for Re= 100 and to Calculate the coefficient of drag and lift over a cylinder by setting the Reynolds number to 10,100,1000,10000 & 100000   Background theory: Vortex shedding is a phenomenon, when the wind blows across a structural…

Procedure, inference, conclusion with snap shots are attached as PDF file. Please find attachement Thank you

AIM: To do a 2D and volumetric mesh of Tesla truck. Procedure:     Examine thoroughly in wire frame mode if any single cons are present if any Remove all single cons   Examine for overlapping surfaces if any delete that Geometry checks were done and error such as cracks between cons were removed lights are meshed with…

AIM: To do the surface wrap for Engine, transmission and gear box Procedure     1. Use Not option to find the unwanted entities in the model. Here rings, spheres are used for creating the fillets so that we can delete this.     Overlapping surfaces are cleared in Gear box   Overlapping surfaces are cleared in transmission…

Aim: To do  the geometrical clean up and surface and voumetric meshing of Given BMW Car Model.  Procedure: 1. Check the car interior and exterior for any overlapping surfaace,  single cons and triplecons. 2. Delete all the unwanted surfaces  3. Use extend, intersect, paste option etc to remove the single…

Aim: To perform the 2D mesh for the given turbocharger model   Procedure: Do the geometry clean up by identifying and  deleting the overlapping surface. thorough examination has to be done to find the overlapping surfaces. Identify the single cons and triple cons and delete all If necessary keep the triple cons Ensure…

Aim:  To mesh the given valve for the mesh size of 1mm, 3mm and 5mm. Procedure: Run the Geometry check for single cons etc. Do the geometry clean up by filling the hole , cut the faces which is exceeding above the mesh length Assign the PID for the desired surfaces. Here PID assigned for base, valve head, inlet, outlet,…
