摘要: 应用数值模拟方法对水下爆炸产生的诸如气泡脉动规律、脉动周期、水中冲击波压力的变化等特性进行了研究。给出了不同装药水下爆炸产生的气泡半径脉动的一些规律、脉动周期变化规律、气泡与水交界面处的压力曲线、爆炸产生的水中冲击波压力和速度的变化等结果。Abstract: The characteristics of underwater explosions such as pulsation law and pulsation cycle of bubbles, and pressure time histories of shock waves in water were investigated numerically. Numerical results of the characteristics are given in this paper.
