Week 2 - Flow over a Cylinder.

 AIM: Simulate the flow over a cylinder and explain the phenomenon of Karman vortex street. Understanding the vortex shedding for different Reynolds numbers by changing the inlet velocities accordingly. Create a monitor point behind the cylinder at a distance 4 times the diameter which can be used to calculate and…

OBJECTIVE: For this challenge, we have created two versions of the mixing tee. One of them is longer than the other. Our job is to set up steady-state simulations to compare the mixing effectiveness when hot inlet temperature is 360C & the Cold inlet is at 190C.  Use the k-epsilon and k-omega SST model for the…

1] AIM - To generate volumetric mesh for BMW car for CFD applications. 2] OBJECTIVE -  To create half model of the given geometry and solve all geometrical errors.  To perform topology cleanup,generate PID's and generate surface mesh.  To create wind tunnel. To generate volumetric mesh from the surface…

Aim/Objective : To do surface wrap over assembled parts (engine,transmission and gear box) .   Target length for Wrap = 3mm To Assemblet Engine, Transmission and Gear Box together with Merge Option in ANSA.   What is Surface Wrap? The surface wrap is used to create a watertight surface mesh which replicates…

Aim:           For the given model of a turbocharger, check for the geometrical errors to make appropriate volumes. Create and assign PIDs accordingly. Create surface mesh and use that to create a volumetric mesh.   Objective: 1. Perform surface mesh with the given target lengths as per PIDs.…

AimFor the given model, check for the geometrical errors and perform Topology cleanup accordingly. Set three different target lengths as three different cases and mesh the model. Target length = 1mm, 3 mm and 5 mm (i.e. 3 cases)Element type = TriaObjective:            Apply any one target…

OBJECTIVE: To solve Steady and Unsteady state 2D Heat Conduction Equation by using the point iterative techniques such as Jacobi, Gauss Seidel & Successive over-relaxation for both implicit and explicit schemes using MATLAB. Problem statement: Computation area is to be a square. Assume nx = ny [No. of…

OBJECTIVE: We have to derive the following 4th order approximation of the second-order derivative using:- 1. Central difference 2. Skewed right-sided difference 3. Skewed left-sided difference Also, we have to  prove that our skewed schemes are fourth-order accurate.  Therefore we have to write a program in Matlab…
