Bubble has significant applications in ocean engineering. Aiming at the difficulty of conducting the underwater explosion bubble experiment with large charge in deep water, this paper adopts a new way to deal with this problem. On the basis of similarity theory, it is found that by considering the scaling relationship of gravitational acceleration, the explosion bubble with small charge in shallow water can satisfy the similar relationship with the explosion bubble with large charge in deep water. Therefore, the dynamic characteristics of the explosion bubble with large charge in deep water can be realized by changing the gravitational acceleration. With the assumption that the liquid is inviscid and incompressible, the bubble dynamics are solved by the Euler equations with the finite volume method, and the motion of the bubble interface is tracked by the front tracking method. Based on this model, the bubble collapse characteristics near a solid wall under different hypergravity environments are studied systematically. The results show that the bubble motion, the formation position of the bubble jet, the liquid jet velocity, and the pressure induced by the bubble will change significantly under different hypergravity environments.

Bubble在海洋工程中具有重要的应用。针对深水大爆炸水下爆炸气泡实验的难点，本文提出了一种解决这一问题的新方法。根据相似理论，发现通过考虑重力加速度的比例关系，浅水装药量小的爆炸气泡可以满足与深水装药量大的气泡的相似关系。因此，可以通过改变重力加速度来实现深水中带大量电荷的爆炸气泡的动态特性。假设液体是无粘性且不可压缩的，则气泡的动力学可通过有限体积法通过欧拉方程求解，气泡界面的运动通过前跟踪方法进行跟踪。基于该模型，系统研究了不同超重力环境下固体壁附近的气泡破裂特性。结果表明，在不同的超重力环境下，气泡运动，气泡喷射的形成位置，液体喷射速度和气泡引起的压力将发生显着变化。
