Three Dimensional Simulation of Hydraulic Phenomenon around Wave-Dissipating Blocks by MPS method

In this study, hydraulic phenomenon around wave dissipating blocks is simulated by a three dimensional MPS method with a precise gradient operator and penalty method. This MPS method solves the pressure oscillation and the fluid particle that penetrates through the wall. As an accuracy verification, the authors simulate wave overtopping rate by this MPS method and obtain a similar result compared with two dimensional CADMAS-SURF. In the simulation of wave breaking on seawall of complex shape, the authors obtained good result. The study suggests that this three dimensional MPS is useful to simulate hydraulic phenomenon around wave-dissipating blocks.
