Helm­holtz-Zen­trum Dres­den-Ros­sen­dorf e.V.

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) Multisensor and Multiscale Measurement Techniques for Hydrodynamic Characterization of Flotation Cells.

PhD Student (f/m/d) Multisensor and Multiscale Measurement Techniques for Hydrodynamic Characterization of Flotation Cells

English

Tasks:

  • Measure and analyze flow-field and turbulence quantities, including turbulent kinetic energy (TKE), using PIV/LIF as well as fiber-optic and piezoelectric vibration sensors
  • Investigate gas dispersion in different zones of the flotation cell by determining bubble size distributions (e.g., using optical probes) and/or by applying ultrafast X-ray tomography (e.g., ROFEX)
  • Develop and further improve multi-sensor and imaging-based measurement methods to capture key process variables in different zones of the flotation cell
  • Integrate and interpret data from different sensors and measurement techniques to provide a consistent hydrodynamic validation dataset for flotation-cell CFD studies carried out by collaborating researchers

Requirements:

  • Completed university studies (Master/Diploma) in the field of Process Engineering, Mechanical Engineering, Chemical Engineering, or a comparable discipline
  • Experience or strong interest in fluid dynamics, turbulence, multiphase flows, and bubbly flows
  • Familiarity with multiphase measurement systems (e.g., PIV, piezoelectric vibration sensors)
  • Independent, structured, and reliable way of working in the laboratory
  • Strong problem-solving skills in experimental setup, instrumentation, and measurement campaigns
  • Willingness to collaborate with industrial and academic partners and to participate in experimental campaigns; a secondment of around 3 months in Chile is planned
  • Basic to good programming skills for data analysis and image processing (e.g., MATLAB, Python)
  • Good written and spoken English

What we 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)
  • 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"
