| 摘 要： | 为研究垂直边界面对水下爆炸气泡脉动的影响,根据势流理论建立了垂直边界面条件下水下爆炸气泡运动的理论模型,编制计算程序进行求解。对水下爆炸气泡脉动运动的特点、流场的速度及压力的分布、气泡引起的载荷形式进行了分析,结果表明,此模型能够反映水下爆炸气泡和周围流体介质的运动规律,并能进行定量的计算。

| Abstract: | The vertical boundary has effect on the pulsation of underwater explosion bubble,so the model of the bubble pulsation dynamics of an underwater explosion is established,which is based on the potential flow theory and considering the vertical rigid plane.A computer program is used to solve the model.The pulsation dynamics,the distributing of velocity and pressure in the flow field and the loading of bubble pulsation are analyzed.The results show that the model can correctly describe the dynamic characteristics of the explosion bubble and liquid around it.Quantificational results can be obtained by solving the model. |
