Smoothed particle hydrodynamics for numerical simulation of three-dimensional free surface flow

Jiao Pei-gang, Yiqi Zhou, Wang Xi-cang

Abstract

An efficient smoothed particle hydrodynamics(SPH)method for three-dimensional free surface flow was proposed.The 3D SPH code for dam break was implemented,the simulation results of 3D SPH accorded with that of the 2D SPH results and the experimental results.Numerical simulation results showed that major physics of the dam break could be well captured in the simulation. The proposed SPH method could be easily extended to deal with many other problems of three-dimensional liquid flow if simulation control parameters such as input condition,boundary condition and corresponding equation of state were properly defined.
