| Abstract: | When a body is launched underwater by gas ejection,a trailing cavity is formed on the aft-end of the body. A modified MAC method was used to numerically simulate the development process of the trailing cavity.The configuration of flow field around the trailing cavity was established,and the effect of the development of the cavity on the pressure distribution on the wall of the launching platform was studied. |
