| Abstract: | 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. |
