摘要: 燃气-蒸汽弹射过程中,导弹尾部离筒后的强烈水气交互作用形成的筒口气泡对导弹运动有一定的影响。利用动网格技术和MIXTURE模型对导弹弹射出筒后筒口气泡的发展情况进行了研究,探究了筒口气泡扩张、收缩和拉断的一系列过程,比较了泡内不同位置的压力变化和压力传递过程,指出了气泡形态跟泡内压力呈负相关的关系。仿真结果可用于工程预报。

Abstract: During the launch of submarine launched missile with a gas-steam ejection system, an outlet cavity is formed because of a strong interaction between water and gas. The development of cavity has an effect on the motion of missile. Dynamic mesh and MIXTURE model are used to simulate the law of development of cavity: expansion, contraction and disruption. Pressures at different locations and the transmission process of pressure are also discussed. The shape of cavity is proved to have a negative correlation with the cavity pressure. The simulation result can be used for engineering prediction.

Key words: fluid mechanics, outlet cavity, submarine launched missile, MIXTURE model
