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: 124/24

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 low dimensional stochastic models for turbulent flow and accurate numerical discretizations of partial differential equations on Cartesian grids.


Project description:

Particles in the atmosphere, which are sucked in by aircraft engines, have a severe impact on the operation and service life of air traffic and aircraft gas turbine components. Calcium, magnesium, aluminum, silicate (CMAS) particles, such as volcanic ash or sand, are particularly problematic: on the one hand due to mechanical friction, which leads to material erosion and abrasion, and on the other hand due to the melting points of the particles, which are sometimes far below the combustion temperature in the engine's combustion chamber. This can result in molten particles sticking to the turbine blades, which has a negative impact on the cooling of the turbine blades and can lead to costly maintenance work. In this project, an Euler-Lagrange method for the simulation of particle interactions with hot turbine surfaces is to be developed and evaluated with test and operating data.

The project is part of a large joint research program with engine manufacturer Rolls-Royce Germany.


These are your responsibilities:
Conducting scientific research as part of the ProFIT Brandenburg business development program:
• Evaluate existing constitutive models for CMAS particles
• Implementation of an Euler-Lagrange CFD method in an in-house code to simulate the interaction of CMAS particles with static and rotating turbine components
• Validation of the simulation model with comparative calculations from the literature and correlation with available in-service observations
• Parameter studies to investigate relevant parameters such as Stokes number, particle loading, viscosity and temperature on adhesion and layer formation
• Presentations and publishing on the respective research topic
• Preparation of contributions for reports and presentations 
• Research-related administrative tasks within the scope of the research project

Your Skills:
We expect an excellent Master degree in engineering or related disciplines. You should have a solid background.

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 equivalent).
•	Numerical fluid mechanics / Computational fluid mechanics
•	Multiphase flow mechanics
•	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.

You should be genuinely interested in theory and scientific work, be able to work independently and think analytically. You should be committed to accurate and trustworthy work with an open-minded personality.

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.
