SPH方法模拟水下爆炸研究进展

Review of applied researches in warship underwater explosion

对SPH方法模拟舰船水下爆炸的主要技术问题及其研究现状进行分析。结果表明,大密度比多相流模拟、三维或基于对称算法的三维模拟、无反射边界等边界的处理是SPH方法实现舰船水下爆炸工程应用的主要技术瓶颈。提出SPH方法实现舰船水下爆炸工程应用的重点研究方向。

The main technical problems and research status of SPH method in simulating warship underwater explosion are analyzed. The results show that the treatments of muhiphase flow of larger density ratio, three dimensional or three dimensional simulations based on symmetric algorithms, non-reflecion boundary and other boundary problems are the main bottleneck technologies of SPH applications in the engineering of warship underwater explosion. Finally,the key research directions of SPH method to solve the problems of warship ianderwater explosion are put forward.
