双药包水下爆炸冲击波及气泡耦合作用规律仿真研究

In order to study the energy output characteristics of the multi-charge underwater explosion, the coupling law of the shock wave pressure, the bubble energy and the generated bubbles of the PBXW-115 single-pack and the double-pack underwater under the same quality were studied. The results show that the shock pressure of the double drug package on its symmetry axis is much larger than that of the single dose package, and the bubble can be larger than the single dose.With the increase of the distance between the two packs, the pulsating cycle and the pulsating pressure gradually decrease.
