Flow over a Mercedes Benz Actros Truck using StarCCM+

This project deals with simulating the flow around a Mercedes Benz Actros truck with and without the trailer attachment, We will be studying the production of wake and how the trailer attachment affects the wake produced by the tractor and the effect this has on the production of drag on the vehicle. Suitable reports and plots will be used to measure the drag coefficient and to assess convergence. Various post processing techniques can be used to provide animations that clearly show the flow patterns.

Flow around an Ahmed Body using StarCCM+

This project deals with simulating the flow around an Ahmed Body, which is a prototypical car model. In order to perform this simulation, a computational domain will be defined in the form of a virtual wind tunnel. The simulation will be run for 25 and 35° slant angles and the flow patterns will be studied for both cases. Multiple cases for various slant angles can be run to show how the separation at the rear takes place and how the wake is affected, ultimately affecting the drag produced by the body. Finally, the results will be compared with the experimental results to get an idea of which solution and turbulence models to use and fine tune the setup to provide the best results.

Modeling and Simulation of flow around an Ahmed Body

In this project, you will be creating a geometry in any of the CAD packages you are comfortable with and setting up the case in Converge Studio by providing appropriate boundary conditions. Also, you will be learning the theory behind how to create a virtual wind tunnel and will be creating it. Through this project, you will be getting a very good insight on the concepts of turbulence modelling, Y+, calculating 1st cell height near the wall and also understand how to make use of Y+ calculator to calculate base grid size. You will get exposed to very strong features of fixed embedding, volume refinement, boundary layer generation which are really important as it gives user, a very good control on the cell count and cell count can easily be optimized using these features.
