Research Assistant - Software Development Flow Solvers (m/f/d)

Supplier: Chair and Institute of Jet Drives and Turbomachines RWTH Aachen University's Institute for Jet Drives and Turbo Machines (IST) is one of the leading university research institutes in the field of modern aviation drives and turbomachines. Embedded in the excellent research landscape of the Technology Region Aachen, we are a strong research partner and offer excellent conditions for entering a scientific or industrial career in aviation, energy technology or adjacent technology fields. The numerical flow simulation (CFD) plays a central role in the design and optimization of modern turbomachines. It enables a detailed analysis of complex aerodynamic processes and contributes significantly to the shortening of development times. In addition to the accuracy of the underlying numerical methods, their efficiency is of crucial importance. Accelerated convergence allows faster evaluation of design variants and more effective use of available computing resources. As part of a research partnership with the DLR Institute of Drive Technology and MTU Aero Engines AG, a multi-grid method with implicit residual smoothing is to be integrated into the TRACE flow dissolving device for convergence acceleration. TRACE is used both in scientific turbomachine research and in the industrial design of aircraft engines and stationary gas turbines. The RWTH is certified as a family-friendly university. RWTH offers a variety of health, counselling and prevention services (e.g. university sports) as part of a university health management. There is a wide range of training and the possibility of obtaining a job ticket for employees and civil servants.

Your duties You implement and validate a multi-grid process with implicit residual smoothing in the flow dissolving TRACE. Your tasks in detail: Conception of a multi-grid process with implicit residual smoothing for the CFD-solder TRACE Implementation of the procedure in TRACE with integration into existing structures of the solver Numerical validation based on academic test cases and realistic applications Analysis of the efficiency increase and development of best practice recommendations for users Documentation of results The integration of your research into a doctorate is expressly provided and is actively supported by us.

Your profile A prerequisite for the recruitment is a completed university degree (master or comparable) in the field of mechanical engineering, aerospace technology or a comparable engineering discipline. Required qualifications are: Good to very good studies knowledge of the aerodynamics of turbomachines Knowledge of numerical fluid mechanics and numerical mathematics Safe handling of programming languages (e.g. C/C++, Python) Experience in handling HPC systems of advantage Good or very good knowledge of German and English in word and writing Self-employed, structured and targeted Joy of scientific work and analytical thinking

The employment is in the employment relationship. The place shall be occupied at the next possible time and shall be limited to 4 years. It is a full-time job. There is a doctoral opportunity. The grouping depends on the TV-L. The place is rated with EG 13 TV-L. The job description is aimed at all sexes. We want to promote the careers of women at RWTH Aachen University and are therefore looking forward to applicants. Women are preferably taken into account in the case of equal suitability, competence and professional performance, provided You are underrepresented in the organisational unit and, if not in the person of a competitor, outweigh the reasons. Applications for suitable people with difficulty are expressly desired. For the purposes of equal treatment, we ask you to waive an application photo.
