Abstract

Abstract:

An efficient smoothed particle hydrodynamics (SPH) method for three-dimensional free surface flow was proposed. The 3D SPH code fordam 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 thedam 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 conditionand corresponding equation of state were properly defined.
