| 摘 要： | 对光滑粒子流体动力学法(SPH方法)的发展背景、理论基础等进行介绍,总结了SPH方法在溃坝、海冰和河冰模拟、船舶流体力学等具有自由表面的流体研究中的应用现状,认为作为一种无网格的纯Lagrange方法,SPH方法较传统的基于网格的模拟方法具有不可比拟的优势。最后分析了SPH方法的缺陷及目前研究中的不足,并就今后的研究方向和发展趋势提出自己的看法。

| Abstract: | The development background and theoretical basis of the smoothed particle hydrodynamics(SPH) were introduced.The application situations of the SPH method to the studies on free surface flows in aspects of the dam-break,sea ice,river ice and ship hydrodynamics etc.were reviewed.As a meshless pure Lagrange method,the SPH method was superior compared with the traditional simulation methods based on meshes.Finally,the shortcomings of the SPH method as well as the shortages in their studies were investigated,and... |
