Abstract

Experiments were carried out on the propagation of shock wave and bubble impulse based on the spherical TNT and cylindrical aluminized explosives. Underwater explosion under gravitation was simulated and analyzed using MSC. DYTRAN finite element analysis software. Computational results were compared with experimental results, showing that the structure-fluid coupling method can precisely simulate the motion of bubbles. The relationship between equations of state and motion of bubbles were analyzed and summarized. The research has its value in correlating theoretical research and engineering calculations.
