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-dimensional free surface flows,such as dam-break,impact-wave and water-entry.To simulate these problems,the SPH method is combined with weakly compressible model,XSPH method,artificial viscousity and six degrees of freedom equation of motion.Moreover,to improve the computational efficiency,the parallelization of SPH method using MPI paradigm is implemented,each processor contains a subdomain and communicates boundary particles during the simulation.
