Explosion Effect of Liquid Explosives Under Water

4 Explosion Effect of Liquid Explosives Under Water 

The above-discussed shock waves are in unlimited water medium. The real water medium has free surface (intersurface of water-air) and water bottom. After the explosion of liquid explosives, the shock waves in water reach the free surface or water bottom, and then reflection is generated. 

Because of the reflection of sparse waves from free surface, the damage of explosion in water is obviously improved compared to that on ground. This property can be used to improve the utilization rate of explosives. But if the explosion occurs in deep enough water, the bubbles are dispersed or dissolved before they reach the free surface. Now there is no fountain. For general explosives, the depth is calculated by below equation. 

h is the depth of explosives in water and W is the mass of explosives
