光滑粒子方法是一 种新近发展 的可用于流动模拟的无网格数值方法 ,理论上能够适应任意变形 ,在模拟流体流动的剧烈变形时有显著的优势 但是流动的初始、边界条件和一些计算数的选取都会对计算结果产生较大 的影响 作者基于 方法 的基

本原理 ,

全面考虑了各种定解条件的设置 ,

独立发展 了一 套用于模拟不可压 自由表面流动的

程序 ,

并应用 于溃坝流动的模拟 之 中 模拟结果 与 和 经典 的结果非常吻合 ,验证 了方法的准确性,为 方法的一 步发展和广泛应用奠定 了一定的基础-Smoothed particle method is a newly developed flow simulation can be used for meshless numerical method, in theory, able to adapt to any deformation, fluid flow in the simulation of intense deformation has significant advantages, but the initial flow, boundary conditions and some of the calculations select the number of results will have a greater impact on the basic principles of the author based methods, fully taking into account the set of boundary conditions, a set of independent development for incompressible free surface flow simulation program, and applied to the dam break flow into the simulation results with the simulation results are very consistent and classic to verify the accuracy of the method, the method further development and wide application to lay a certain foundation
