A numerical simulation of the cavity, supercavity flow 二维空化、超空化流动的数值模拟
A series of experiments about supercavitating flow around underwater vehicle are conducted in a high-speed cavitation water tunnel to investigate the pressure distribution in the supercavity and the properties of rear flow field near the supercavity. 利用循环式空泡水洞,对航行体模型的通气超空泡内压强分布及其对空泡尾部流场的影响情况进行了实验研究。
The potential theory neglects the vapor in the supercavity, because the mass in the cavity is so tiny that its inertial applies little effect on the dynamics of the water flow. 势流方法,不考虑空穴内汽体;这是因为汽体质量太小,其惯性对水流动力学条件影响很小。
