Abstract

Plunging wave breaking is one of the most violent air-water interaction phenomena. A thorough understanding of the physics of this highly unsteady two-phase flow phenomena is important for investigating ship bow breaking waves. This paper focuses on the hydrodynamic simulation of the whole process of plunging breaking waves generated by a sharp wedge-shaped bow and the velocity and vorticity field in the region of the bow and in the breaking waves. A numerical towing tank is constructed with a vertical wedge fixed in the middle of the tank and the incident flow set as uniform. The numerical results of the bow wave profile at different locations in the vicinity of the bow are compared to experiments to validate the two-phase flow solver. Further numerical analysis is performed for different inlet flow velocity to investigate the influence of Froude number on the shape of bow breaking waves.
