In this dissertation a method for the prediction of hydroacoustic sound emission of propellers in the early design stage is developed. The sound prediction is performed by a hybride approach. A boundary element method is used for flow calculation and the Ffowcs Williams-Hawkings-equation for hydroacoustic sound prediction, extended to considering reflections.
The method is validated by a calculation of a propeller behind a ship. The calculated sound pressure levels does agree well with measured data. Additional the simulation results are compared with exisitng guidelines for processing of measurement data.
