空泡螺旋桨在任意形状船体上诱导的脉动压力数值预报方法研究

摘要

研究了空泡螺旋桨在任意形状船体上诱导的脉动压力的一种数值预报方法.该方法采取了在船体表面布置偶极子的办法，取代了传统的固壁因子.对放置在自由表面上的平板船体模型进行了计算，并将计算结果同理论估算方法的结果进行了比较，说明本计算方法是可行的.%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.
