Abstract

Subroutines which define the hydrostatic pressure and boundary conditions of the three-dimension fluid field are developed based on MSC. DYTRAN software. The volume-acceleration model is introduced to determine the initial condition of bubble pulsation in underwater explosion. The numerical simulations are compared with the results of validated experimental data. The calculated results of pulsation radius and period of single bubble are well agreement with the experimental results. The interaction of two bubbles is studied systematically, and the relative law of that the dynamic behaviors of bubbles are closely related distance and initial angle is summarized. The bubble model and numerical simulation arevaluable to correlative theory research and engineering calculation.
