Coupling Vof/Plic and Embedding Method for Simulating Wave Breaking on A Sloping Beach

A 2-D numerical model was developed to simulate wave breaking on a sloping beach. The model solves the Reynolds Averaged Navier-Stokes (RANS) equations coupled with the k-s turbulence closure model. To track free surface configurations, the volume of fluid with piecewise linear interface calculation (VOF/PLIC) is employed. An embedding method (EB) is also used to treat complex bottom topography. Coupling these two methods for simulating wave breaking on a sloping beach, good agreement between numerical results and laboratory observations is found for spilling breaker. Wave breaking characteristics is in terms of free surface profiles, mean velocities and wave heights based on the numerical results. Turbulence transports under wave breaking were also investigated.
