PhD Student (f/m/d) Experimental Investigation of Hydrodynamics in Turbulent Flotation Cells

With cutting-edge research in the fields of ENERGY, HEALTH and MATTER, around 1,500 employees from more than 70 nations at Helmholtz-Zentrum Dresden-Rossendorf (HZDR) are committed to mastering the great challenges facing society today.

The Institute of Fluid Dynamics is conducting basic and applied research in the fields of thermo-fluid dynamics and magnetohydrodynamics in order to improve the sustainability, the energy efficiency and the safety of industrial processes.

The Department of Fluid Dynamics Resource Technology Processes is looking for a PhD Student (f/m/d) Experimental Investigation of Hydrodynamics in Turbulent Flotation Cells. 

Your tasks

• Apply and further develop optical and sensor-based measurement techniques to capture key hydrodynamic parameters in flotation cells
• Analyze multiphase flow behavior, including turbulence, gas dispersion, bubble size distributions, and time-resolved flow structures
• Integrate, document, and communicate experimental findings through data interpretation, reports, scientific publications, and project meetings

Your profile

• Completed university studies (Master/Diploma) in the field of Process Engineering, Mechanical Engineering, Chemical Engineering, or a comparable discipline
• Experimental background in fluid dynamics, particularly in bubbly and multiphase flows
• Hands-on experience with optical or sensor-based measurement techniques for hydrodynamic characterization, such as PIV, PTV, LIF, vibro-acoustic sensors, or fiber-optic sensors
• Basic to good programming skills for data analysis and image processing (e.g., MATLAB, Python)
• Strong problem-solving skills in experimental setup, instrumentation, and measurement campaigns
• Good teamwork and communication skills in an interdisciplinary project environment
• Good written and spoken English

Our offer

• A vibrant research community in an open, diverse and international work environment
• Scientific excellence and extensive professional networking opportunities
• A structured PhD program with a comprehensive range of continuing education and networking opportunities - more information about the PhD program at the HZDR can be found here
• Salary and social benefits in accordance with the collective agreement for the public sector (TVöD-Bund) including 30 days of paid holiday leave, company pension scheme (VBL)
• Depending on the personal qualifications, the candidate may be classified in salary group 13 according to TVöD-Bund
• We support a good work-life balance with the possibility of part-time employment, mobile working and flexible working hours
• Numerous company health management offerings
• Employee discounts with well-known providers via the platform Corporate Benefits
• An employer subsidy for the "Deutschland-Ticket Jobticket"

We look forward to receiving your application documents (including cover letter, CV, diplomas/transcripts, etc.), which you can submit via our online-application-system.
