NUMERICAL SIMULATION OF MULTIDIRECTIONAL WAVES WITH FULL-SPECTRUM USING DUALSPHYSICS

摘要

The numerical model for circular wave basin were developed using DualSPHysics based on Smoothed Particle Hydrodynamics to generate short-crested wave. The recreation of short-crested wave was achieved using Pierson Moskowitz spectrum and cosin~(2s) spreading function with spreading value s. It is found that this numerical tank model could successfully reproduced not only long-crested but short-crested waves using 168 hinged-flap type wave makers.
