| Abstract: | A computational method for prediction of pressure fluctuation induced by cavitating propeller on hulls of arbitrary shape is reported. In this method, the previous steady body factor replaced by normal depoles.The calculation result about a flat plate positioned on the free water surface is gived.The compare with a theoretic predictive method of force fluctuation induced by cavitating propeller on flat plate proves the practicability of this method. |
