APPLICABILITY OF MPS METHOD TO BREAKING AND POST-BREAKING OF SOLITARY WAVES

As a meshfree particlemethod, the MPS (Moving Particle Semi-implicit) method is an efficient numerical tool for simulating flowswith complicated behavior of water surface, such aswave breaking. In this paper, the MPS method hasbeen applied to solve the Navier-Stokes equation for simulating the breaking and post-breaking of solitary waves on a uniform slope. The high precision of MPS method in the simulation of violent free surface flows, likethebreaking waves, isconfirmed through both quantitative and qualitative comparisons to other numerical results by the BEM or the VOF and experimental data. The process of splashup which ishard to be simulated by conventionalgrid-based methods is alsowell reproduced by the MPS method.
