As member of the Helmholtz Association of German Research Centers, the Helmholtz-Zentrum Dresden – Rossendorf (HZDR) employs about 1,200 people. The Center's focus is on interdisciplinary research in the areas energy, health, and matter.

The Institute of Fluid Dynamics of HZDR has a strong focus on the resuspension of micron particles in turbulent flows. It invites applications for a six-month internship to investigate experimentally the particle detachment from wall surfaces in turbulent flows. The position is available immediately. Kindly submit your completed application (including cover letter, CV, diplomas/transcripts, etc.) via our Online-application-system.

Advances in the generation of functional surfaces (i.e. surfaces with well-defined asperities) make it possible to design self-cleaning surfaces. The automotive industry may for instance benefit from such advances. The aim of the project is to study experimentally the detachment of “dust” particles (glass beads with diameters ranging from 10 to 50 µm) on smooth substrates with precisely defined asperities (size of the asperities about 1 µm). The collision of the rolling dust particles with the asperities is expected to boost the resuspension, thereby leading to an enhanced self-cleaning effect of such surfaces.

The tasks of the project will involve:

• Perform a literature survey on the resuspension of micron-particles in turbulent flows
• Design a small wind tunnel to study the particle detachment from wall surfaces with well-defined asperities
• Use of high-speed cameras to visualize the particle detachment in turbulent flows
