In order to fill a fixed-term position in full-time (39.83 hours/week = 100%) starting October 1st, 2026, we are looking for a Research Assistant (m/f/x) – Numerical and experimental work The Chair of Thermal Turbomachines and Aeroengines in the Faculty of Mechanical Engineering at the Ruhr University Bochum (LSTTF) is among the leading research groups in Germany in the field of experimental and numerical investigation of energy transformation systems. Cutting-edge numerical and experimental research is carried out, covering a broad spectrum of topics from classic turbomachinery aerothermodynamics, aeroelastics, two-phase flows and non-ideal compressible fluid dynamics with a strong focus on the design and optimisation of modern fluid energy machines to be employed in innovative cycles for power generation, energy storage and process engineering and using essentially non-conventional working fluids (such as steam, supercritical as well as transcritical CO2 flow, hydrogen, ammonia, organic fluids and mixtures). We look for a highly motivated, enthusiastic and highly qualified research assistant, who will carry out the proposed research engaging in numerical as well as experimental investigations with the possibility of obtaining a Doctorate. Scope: full-time Duration: fixed-term, 3 years Start: starting October 1st, 2026 Apply by: 2026-07-31 Your tasks: Within a new research project technological issues are addressed in close cooperation with industrial and academic partners which are at the core of the conception and realization of new radial expander stages for use in compressed air storage systems. While an optimized aerothermodynamic design can lead to a considerable increase in the efficiency of the machines, the aerodynamic forces acting on the blades can compromise their structural integrity, especially at higher power levels. Accurate scaling methods are necessary to overcome these issues. The project aims to develop a generalized scaling procedure for high power output based on scale-resolving simulations and precise flow measurements. The in-house CFD-solver SharC will be further developed and adopted for all numerical investigations which will be validated against measurements performed on the Chair’s own axial and radial turbine testrigs. Your profile: - M.Sc. or Diploma in the field of Engineering or Physics - Deep knowledge (Master level) of fluid energy machines aerodynamics and thermodynamics as well as turbulence modelling - Familiarity with steady and unsteady intrusive velocity and pressure measurement techniques (HWA, pneumatic multi-hole probes, time-resolved pressure measurements) - Familiarity with laboratory data acquisition systems and software (such as LabView) and with the appropriate scripting and user coding - Very good knowledge (Master level) of the thermodynamic modelling of non-ideal fluids and mixtures - Experience in setting up, running and post-processing numerical simulations of turbomachinery flow simulations - Basic knowledge of construction and technical drawing - Fluency in German (C1 level, in word and writing) - Excellent ability to communicate and work in a heterogeneous team [https://jobs.ruhr-uni-bochum.de/jobposting/cbe6541fec6f3cd3f251fc52ce108a263fe068c40?ref=AfA](https://jobs.ruhr-uni-bochum.de/jobposting/cbe6541fec6f3cd3f251fc52ce108a263fe068c40?ref=AfA)
