30 credits – Boundary Conditions for Bus Engine Room Computational Fluid Dynamic, CFD i Sodertalje

Scania is now undergoing a transformation from being a supplier of trucks, buses and engines to a supplier of complete and sustainable transport solutions.

A thesis project at Scania is an excellent way of making contacts for your future working life. Many of our current employees started their career with a thesis project.

Background:
Air Management is a one of the two big responsibilities at RBNK. Air Management involves the movement of the air inside the engine compartment and through the cooling packages and it also incorporates the heat transfer in the engine compartment which is due to the fact that temperatures also play a vital role in air management. 

During the design work CFD simulations are very helpful in order to understand the cooling airflow at different operating points and the corresponding temperature distribution. By using a simulation driven development process many different designs can be explored without building physical prototypes. Also at later stages of the development process, when physical prototypes exist, simulations are used to evaluate and select different concepts.

In order to perform simulations well defined and relevant boundary conditions are needed. The more accurately the boundary conditions are measured the more accurate the simulations can be. A general overhaul of the most critical boundary conditions for engine compartment simulations is needed to increase the confidence in the current simulation models.

Target:
The thesis work is regarding how to find the relevant boundary conditions for two engine load cases, in order to have better and more reliable simulations.

Assignment:
You will within the thesis work:

• Identify two load cases valuable to simulate.
• Identify the hot/cold key parts for the two load cases.
• Compare physical measurement with CFD simulation.
• Create a process for how to use physical measurements for a more accurate CFD simulation.
