Week 3 Challenge : CFD meshing on Turbocharger

In this Challenge, we are going to use conjugate heat transfer analysis to analyse the max temperature attained by the graphics card and also identify the hotspot region for the same.   Pre-Processing: 1) Load the body in Space-claim. 2) Go to workbench and select share topology. With Share topology enabled we will have…

Rayleigh Instability is a hydrodynamic instability that occurs at the interface of two fluids of different densities. Traditionally, the top fluid will be heavier and bottom fluid will be lighter and the gravity will create the instability between the two which leads to mixing and interpenetration of the fluids. This instability…

CHT is an analysis or simulation of heat transfer phenomena where Conduction and Convection takes place simultaneously. It is typically used for studying heat transfer between Solid surfaces like wall and surrounding fluid elements like air, oil etc. This type of analysis is used, where heat transfer play major role. Some…

Q1. Ahmed body is a benchmark for validating simulation tool. As we all know major factor in validating any car model is its aerodynamic efficiency. If a car is aerodynamically efficient i.e., less drag is generated by the car, its fuel efficiency will also increase. But for complex car model it is difficult to validate…

Aim: To run simulation for flow over cylinder to calculate Strouhal Number for steady and unsteady state and Drag and Lift coefficient for Different Reynold number case. Procedure: We need to create Surface such that inlet edge is 10XD away from cylinder centre and outlet edge is 20XD away from cylinder centre. The top…

Aim: To perform a Fluid flow analysis of a Mixing Tee component using hot and cold air through 2 inlets. We will define the relation between the length of the mixing tee component and the temperature of the air at the outlet. Also, the variation in the outlet temperature based on the velocity of cold Air. We will also…

Aim: To solve geometrical errors in the given model and to give mesh as per quality criteria, to create good mesh. Procedure: Once the car model is loaded, we must start with the surface clean-up: As we can see the car model is symmetrical. So, we can delete half of the model, to make our updates easier. Once half model…

Aim: To create Surface mesh and Volumetric mesh of a turbo charger. Procedure: Once Turbo charger is loaded in ANSA, we must first proceed with surface correction using Topo deck: As we see some overlapped surfaces, I deleted those by carefully inspecting the surface needed and the surface that are extra. After that, I…

Aim: To create mesh of a pressure valve, and observe the difference between, 3 different mesh lengths.   Procedure: Once the pressure valve is loaded in Ansa first, we must proceed with surface corrections: Faces can be created using new option under faces. Based on the type of new faces to be created select the CONS.…
