Prediction of propeller-induced hull pressure fluctuations
The cavitating propeller often forms the primary source of noise and vibration on board ships. The propeller induces hydroacoustic pressure fluctuations due to the passing blades and, more importantly, the dynamic activity of cavities in the propeller’s immediate vicinity. The accurate prediction of the resulting vibratory hull-excitation forces is indispensable in the ship design process, but is not always warranted. From this follows the main objective of the thesis, which is the development of improved prediction capabilities for propeller-induced hull-excitation forces based on experimental and computational procedures.
