| 摘 要： | 本文用空泡预报的结果,在桨叶面和尾涡面布置强度已知的源汇和偶极子,计算了空泡螺旋桨诱导的脉动压力.真实的船体表面形状可以通过在船体表面布置偶极子来考虑,求得船体表面的偶极子强度后,通过Bernoulli方程可得到船体表面的脉动压力.为了便于同已有的试验数据进行比较,本文计算了空泡螺旋桨诱导的平板脉动压力.

| Abstract: | The pressure fluctuations induced by the cavitating propellers was calculated by placing the sources and dipoles whose strength is known on the blade surface and the wake surface.The true shape of the hull can be considered by distributing dipoles on the hull surface.The pressure fluctuations on hull surface can be calculated through Bernoulli's equation.In order to compare the numerical results by the proposed method with the existing experimental data,the pressure fluctuations generated by the propellers on a flat plate are presented. |
