Numerical simulation of Three-dimensional Free Surface Flows by Smoothed Particle Hydrodynamics

摘要

In this paper, SPH method is use to simulate some three-dimensionalrnfree surface flows, such as dam-break, impact-wave and water-entry. To simulaternthese problems, the SPH method is combined with weakly compressible model,rnXSPH method, artificial viscousity and six degrees of freedom equation of motion.rnMoreover, to improve the computational efficiency, the parallelization of SPHrnmethod using MPI paradigm is implemented, each processor contains a subdomainrnand communicates boundary particles during the simulation.
