Defocusing particle tracking velocimetry (defocusing PTV) is applied in various levels of
magnification to investigate the flow in an open wet clutch with radial grooving. The …

A volumetric, three component microscopic particle tracking velocimetry (μPTV) system is
presented which relies on single window optical access for both high-speed tracer …

A multi-aperture 3d 3c micro PTV system is presented which relies on single window optical
access for both high-speed tracer illumination and image recording. Similar to …

The present work improves the fundamental understanding of the fluid flow that passes
through an open wet clutch, and its contribution to the generated drag torque and the …

Precise knowledge of the near-wall velocity profiles for turbulent, wall-bounded flows is of
great interest for a large variety of research topics. Besides the academic interest many …
