Theoretical study of the pulsation dynamics of an underwater explosion bubble with a vertical rigid plane

Zhang Zhen-hua

Open publisher page 1 citations

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.
