The Chair of Hydraulic Fluid Machinery (HSM) at the Faculty of Mechanical Engineering is looking for a 

research associate (m,f,x) Development of 3D and 1D Simulation Methods (CFD) for cavitating and turbulent flow in Hydraulic Machinery and Components for 2,5 years with 39,83 hours per week, TV-L E14

The main research topic of the Chair of Hydraulic Fluid Machinery (HSM) is the development of customised CFD methods for the numerical simulation of multiphase flow in fluid machinery and their components. Application examples cover rotating and displacement machinery, injection systems and basic investigations. We focus on the customised development of numerical schemes and physical models, for example for the computation of cavitation, multiphase and multispecies fluid flow, jet break-up, bubble dynamics and turbulence. Thereby, a bridge is built from basic and methodological research to industrial research and applications on machinery.

The Ruhr-Universität Bochum is one of Germany’s leading research universities, addressing the whole range of academic disciplines. A highly dynamic setting enables researchers and students to work across the traditional boundaries of academic subjects and faculties. To create knowledge networks within and beyond the university is RUB’s declared aim.


The Ruhr-Universität Bochum stands for diversity and equal opportunities. For this reason, we favour a working environment composed of heterogeneous teams, and seek to promote the careers of individuals who are underrepresented in our respective professional areas. The Ruhr-Universität Bochum expressly requests job applications from women. In areas in which they are underrepresented they will be given preference in the case of equivalent qualifications with male candidates. Applications from individuals with disabilities are most welcome.
