The Faculty 1 MINT - Mathematics, Computer Science, Physics, Electrical Engineering and Information Technology is seeking to fill the following position at the Chair of Numerical Mathematics and Scientific in Cottbus as soon as possible:
Research Assistant (m/f/d)
Full-time, E 13 TV-L, Fixed-term employment (3 Years)
Reference Number: 125/24
The Chair of Numerical Mathematics and Scientific Computing at Brandenburg Technical University Cottbus-Senftenberg is active in modeling and simulation of complex engineering problems with a focus on fluid mechanics, turbulent combustion as well as various aspects of high-performance computing. Current research topics focuses on low dimensional stochastic models for turbulent flow and accurate numerical discretizations of partial differential equations on Cartesian grids.
Project description:
The atomization of liquid jets plays an important role in many technical applications. Two examples are the injection process of liquid fuel in gas turbines or spray drying in process engineering. Jet disintegration processes can be simulated using computational fluid dynamics (CFD) methods, whereby large eddy simulation (LES) has established itself as a standard tool for researching and simulating turbulent flows. A major challenge in the application of LES for multiphase flows is the modeling of the non-resolved subgrid scales (SGS) on which, among other things, the primary jet break-up process takes place. In this project, a new stochastic SGS for primary jet break-up will be developed, implemented and evaluated.
These are your responsibilities:
Within this research project funded by the German science foundation DFG you will perform the following tasks:
• Development of a new physical SGS model for primary jet break-up
• Implementation of the model in the well renowned CFD code PARIS for multiphase flow
• Execution of LES simulations on high performance computers
• Analysis of the simulation results
• Presentations and publications on the research topic in English
• Cooperation with project partners in Germany, Austria and the U.S.A.
• Preparation of contributions for reports and presentations
• Other administrative tasks related to research
Your Skills:
A completed academic university degree as defined by the TV-L pay scale (accredited Master's degree / university diploma / equivalent) in a scientific field relevant to the position (mechanical engineering, aerospace engineering, physical engineering, process engineering or comparable). As part of your studies, you should have acquired in-depth knowledge in the following areas:
• Numerical Fluid mechanics including turbulence, multiphase flow and computational fluid mechanics
• Turbulence modeling
• Proven programming experience in C++ or Fortran and Python
You also bring with you the ability to work scientifically, independence, flexibility and good communication skills. With the ability to think analytically and to work diligently and conscientiously, you are an ideal addition to our interdisciplinary team.
Your profile is rounded off by a good command of written and spoken English.
For further information please contact Prof. Dr.-Ing. Michael Oevermann (e-mail: michael.oevermann@b-tu.de, Tel.: +49 (0)355 / 69-2775).
Our offer:
You can expect exciting and varied tasks in a highly innovative research project with several partners. You will take part in international conferences with corresponding publications. The work in the project is ideally suited for a doctorate. In the event of a prospective qualification, opportunities for further employment will be sought after the end of the project.
You can expect extensive opportunities for flexible working hours, such as home office, to enable a better work-life balance and to achieve greater job and result satisfaction through more personal responsibility in the design and implementation of your work.
Become part of the BTU family. We look forward to getting to know you.
