In HSVA’s medium-sized cavitation tunnel, an LDV-service (Laser Doppler Velocimeter) was used to measure the three-dimensional flow field in the slipstream of different model propellers. Three propellers were investigated with the same main dimensions except for different skew.
The propellers were designed especially for this investigation. The skew angles were 0 degrees, 21 degrees and 62 degrees. Most measurements were done at a distance of 0.3 D behind the propellers at uniform inflow.
