In a propeller propulsion system, due to the torque working on the propeller, a rotational motion of the fluid is generated. This rotational motion, expressed as a swirl component in the slipstream, does not result in any useful propulsive power, but causes a decrease in propeller efficiency. By recovering the momentum in the crosswise direction...

The goal of this study is to test the hypothesis that the resonance of a tip vortex cavity is responsible for high-amplitude broadband pressure-fluctuations, typically between 40 and 70 Hz,Hz, for a full scale propeller. This is achieved with a model propeller in a cavitation tunnel. Simultaneous high-speed video shadowgraphy and sound...

De uitgevoerde studie kent een drietal onderdelen: selectie relevante boegschroefinstallaties, bepaling initiele stroomsnelheid ter plaatse van de boegschroef, en bepaling van de stroomsnelheid in de boegstraal. Allereerst is een inventarisatie gemaakt van de geïnstalleerde typen boegschroefinstallaties resulterend in een drietal hoofdtypen. Van...
