Lehrstuhl für Strömungsmechanik - Chair of Fluid Mechanics


The fluid mechanics laboratory includes several experimental equipments for the testing of rotating machinery ranging from the centrifugal separation to different kinds of fluid machines. Test rigs for filtration, cleaning, coating can be used as well. Various experimental equipments for the visualization and measurement of two-phase flows are available for research and teaching.

Equipment includes high-speed camera, thermal imaging infrared cameras, hot-wire anemometry, particle-image velocimetry (PIV), particle-tracking velocimetry (PTV), shadowgraphy and various other flow visualization and measuring techniques. Specific diagnostic methods like exhaust measurement systems can be used in research projects.

The computational laboratory includes a High Performance computing cluster with 2500 cores and several high-end Linux workstations. For teaching and student projects, a computational lab with 20 workstations can be used.
