NUMERICAL SIMULATION OF SAND IN PLUNGING BREAKERS

[摘要] A discrete vortex model has been applied to describe plunging breakers. The wave breaking is represented by a jet of water impinging on the surface in front of the wave crest. The suspension of sediment has been modelled by a mixed diffusion - convection scheme. Preliminary results in the form of vector plots of the flow field and concentration profiles are presented.
