Jobbtitel:
2 Ph.D. positions in turbulent combustion modeling and CFD

Arbetsbeskrivning:
Information about the research/the project/the division Governments as well as customers throughout the world are requesting internal combustion engines with higher efficiencies and lower emissions. Stringent future emission standards put severe pressure on the research and development departments of all engine manufactures to have the required engine technology market ready in time. Multidimensional numerical engine combustion simulations using techniques of computational fluid dynamics (CFD) are nowadays an integral part of engine research and development. The purpose of both projects is the development and assessment of new turbulent combustion models with the potential to be truly predictive not only in classical combustion modes and regimes but -- even more important -- under conditions not covered by standard combustion models. Both projects utilize the linear-eddy model (LEM) as a combustion model. In the first project the overall modeling strategy used is called LES-LEM and is based on large-eddy simulation (LES) of turbulent flow combined with the linear-eddy model (LEM) as a sub-grid combustion model. This project is more fundamental and funded by the Swedish Research Council (VR). Investigations will focus mostly on laboratory flames with detailed existiing experimental datasets. The second project utilized LEM in representative way within a RANS turbulence modeling approach called RILEM – Representative Interactive Linear-Eddy Model. The second project is more applied and will focus on specific engine applications.  The positions are located within the Division of Combustion and Propulsion Systems at the Department of Applied Mechanics and Maritime Sciences, Chalmers University of Technology, Gothenburg, Sweden. The research at the Division of Combustion covers a wide range of topics related to internal combustion engines of both fundamental and applied character.  Major responsibilities As a PhD student in these projects you will develop and apply CFD models for LES and RANS simulations of turbulent combustion. The projects require extended periods of programming and model development (a bit more for the VR project). The successful candidates are expected to present the projects progress at international conferences and local meetings as well as to write articles to be published in research journals of highest quality. Position summary Full-time temporary employment. The position is limited to a maximum of five years. Qualifications For the positions a master's level degree awarded by an internationally recognized university in Mechanical Engineering, Engineering Physics, Physics, or Applied Mathematics is mandatory. The candidates should have very good knowledge in fluid mechanics, turbulence theory, and thermodynamics. Practical experience in C++ programming, the Linux operating system and strong knowledge in Computational Fluid Dynamics (CFD) are mandatory for this position. The suitable candidates should be aware of the fact that the position requires extended periods of programming, model development, post-processing and high performance computing. Therefore, the ideal candidates should have some passion for computer simulations and modeling going beyond the usual interest in programming. Good communication skills to work in a bigger research team are necessary as well. Very good englisch writing skills are mandatory as well. To qualify as a PhD student, you must have a master's level degree corresponding to at least 240 higher education credits in a relevant field. Application procedure The application should be marked with Ref 20180448 and written in English. The application should be sent electronically and be attached as pdf-files, as below: CV: (Please name the document: CV, Family name, Ref. number) • CV • Other, for example previous employments or leadership qualifications and positions of trust. • Two references that we can contact. Personal letter: (Please name the document as: Personal letter, Family name, Ref. number) • 1-3 pages where you introduce yourself and present your qualifications. • Previous research fields and main research results. • Future goals and research focus. Are there any specific projects and research issues you are primarily interested in? Other documents: • Copies of bachelor and/or master’s thesis. • Attested copies and transcripts of completed education, grades and other certificates, eg. TOEFL test results. Please use the button at the foot of the page to reach the application form. The files may be compressed (zipped). Application deadline: We will do continuous interviewing until both positions are filled.  For questions, please contact: Prof. Michael Oevermann, Combustion and Propulsion Systems, michael.oevermann (at) chalmers.se, +46 31 772 1401
