Breaking Wave Modeling
In the present numerical study, a two-phase flow CFD model REEF3D is used to model the hydrodynamics of wave breaking over a slope. The numerical model is validated against experimental data for spilling and plunging breaker. Further, the geometric properties of the wave profile during breaking are accessed with steepness and asymmetry parameters. Then, the study also examines the undertow profiles and turbulence intensity of each breaker in the surf zone. The prominent free surface flow features associated with the breaking process including the development of the overturning wave crest and the splash-up are well represented in the numerical simulations.
