Applicability of particle level set method for simulation of breaking waves

Abstract

We investigate the applicability of the Hybrid Particle Level Set (HPLS) method for the simulation of breaking waves by analyzing its performance in modeling sloshing waves and the collapse of a water column in a confined tank. It is found that commonly used restrictions that delete aggressively escaping particles also remove flow features that an unrestricted version of the HPLS captures. However, the unrestricted HPLS performs badly in flow regions where the water phase becomes thin. The cause of the reduced performance is traced to errors in the reseeding procedure that is necessary to maintain adequate resolution of the surface. © by The International Society of Offshore and Polar Engineers.
