超空泡航行体水下弹道的数值计算

Numerical calculation of underwater trajectory of supercavitating bodies

超空泡状态下的航行体水下弹道的研究涉及固、液、气(汽)三相介质的运动。本文应用细长体理论计算航行体在超空泡状态下的流体动力,成功模拟了超空泡状态下的航行体水下弹道。

The study of underwater trajectory and motion stability of supercaviting bodies,dealing with three kinds of media-solid,liquid, gas （vapor）, is one of the most important problems in mechanics and engineering.In this paper,the theory of slender bodies was used to calculate hydrodynamic forces and to numerically simulate the underwater trajectory of supercaviting bodies, the motion stability of supercaviting bodies was analyzed,too.
