Deadline: 31 Jan. 2013
Job description
In this project you would focus on a regime- and mode-independent combustion modeling approach for turbulent combustion with application to engines. Most of the currently existing combustion models are based on the assumption of fast chemistry and they use different modeling approaches for premixed and non-premixed combustion. However, many of the future engine concepts for low emissions and high efficiency will operate under lean conditions and relatively low temperatures. The application of standard combustion models under such operating conditions is questionable. The main objective of this research project is the development of a regime- and mode-independent combustion model for turbulent combustion which can be used under all engine operating conditions. The scientific approach is based on Computational Fluid Dynamics (CFD) using large-eddy type turbulence modeling (LES), standard spray models, and the Linear-Eddy Model (LEM) as a sub-grid combustion model.
As a Ph.D. student you would:
You should have a Master of Science (Swedish: civilingenjör exam; a four year US bachelor’s degree meets the minimum requirement), preferably in Mechanical Engineering, Applied Physics, Applied Mathematics, Computer Science, or equivalent. Knowledge fluid mechanics is considered essential. Good knowledge of turbulence, combustion science, and numerical methods is highly desirable. Experience with CFD codes and programming skills in compiled languages such as C or C++ are regarded an advantage. You should have a genuine interest and curiosity in the more theoretical aspects of engineering science and should be prepared for a position that involves quite a lot of code development and high performance computing. You will collaborate with several research partners, so the ability to cooperate is considered very important.
Application procedure
The application should be marked with Ref 20120374 and written in English. The application should be sent electronically and be attached as pdf-files, as below:

As a Ph.D. student you would:
- Develop a new coupling scheme between LES and LEM for variable density zero Mach-number flow
- Implement (in C++), test, and validate the model in OpenFOAM
- Optimize the code for high performance computing
- Perform engine related simulations with comparison to other models and experiments
