超空泡鱼雷有关流体动力分析

Analysis of hydrodynamic forces of super-cavitation torpedo

针对从理论上难以解析计算超空泡鱼雷流体动力的问题,阐述了一种超空泡鱼雷流体动力数值计算的简单而有效的方法,该算法具有计算量小、执行速度快的特点,数值计算的结果与试验结论吻合.同时,对超空泡高速鱼雷的有关控制力问题进行了分析.

Due to the difficultyin calculating the hydrodynamic forces of torpedo in super-cavitation flow theoretically, this paper expatiates on a numerical method to calculate the cavity shapes,the velocity and pressure distribution and the hydrodynamic forces of torpedo at zero angle of attack in cavitation flow. The method is simple and valid. It calculates quickly and requires less computer time and memory. The numerical calculating results are compatible well with the experimental data. The paper also analyzes the control forces of high speed torpedo in super-cavitation flow.
