一种新型SPH固壁边界处理的排斥力模型
A Repulsive Model for Solid Boundary Treatment inSmoothed Particle Hydrodynamics
摘要
Abstract
Boundary repulsive method is one of the methods for solid boundary treatment in smoothed particle hydrodynamics (SPH), but the method is difficult to be widely applied due to the lack of unified repulsive model.The short-range repulsive force which describes the acting force between granules in Peridynamic (PD) is introduced to solid boundary treatment model to build a new boundary repulsive model in the framework of SPH.The reliability of the method is verified by two numerical simulation examples including Couette flow and dam-break.Moreover, the repulsive formulation is simple and the parameters are easy to be given.Therefore, the present method provides a new alternative for solid boundary treatment in SPH.关键词
