THE INFLUENCE OF PROPELLER SKEW ON THE VELOCITY FIELD AND TIP VORTEX SHAPE IN THE SLIPSTREAM OF PROPELLERS

A Laser Doppler Velocimeter was used in the Hamburg Ship Model Basin's cavitation tunnel to measure the three-dimensional flow field in the slipstream of three different model propellers. The main dimensions of the propellers were the same except for the skew angles. The measurements yielded a quantitative description of the tip vortices and the influence of propeller skew on the velocity field behind the propellers. According to the authors, a surprising result of the velocity measurements was that a propeller's skew angle has only an insignificant influence on the mean values of the slipstream's flow field.
