The process is very versatile. So far the following measuring tasks, among others, have been undertaken:
- Flow fields in the wake of ship models with and without working propellers
- Rudder dynamics with gap flow
- Decay of vortices on a generic wing
- Vortex flow around bilge keels
- Propeller wash of a thruster on a semi-submersible platform
- Propeller wash in the cavitation tunnel
- Flow around and wake of a submarine model with tower
- Flow around profile sections in the cavitation tunnel
With PIV the whole velocity field is measured in every frame. From the individual recordings the transient evolution of the flow can be visualized and also a mean velocity field can be determined by averaging all recordings. The desired spatial resolution determines the size of the field of view and the achievable number of vectors in the measuring range. The largest achieved measuring range so far had an extension of approximately 400×600 mm, in this case about 6000 vectors. For this task, a stereoscopic PIV system from the company TSI is used. It has a modular design, so that all symmetrical, asymmetrical and independent arrangements of cameras and light sheet can be realized. Thus, for example, it is possible to measure the full depth of the towing tank.
