Abstract
A numerical model for simulating breaking waves on a sloping bed was developed. A RANS (Reynolds Averaged Navier-Stokes) based model and the embedding method for bluff body flows on a solid object were employed by taking account of the fully nonlinear, viscous and turbulent effects on the wave breaking problem. Based on a staggered computational mesh, an explicit numerical algorithm is employed with a predictor-corrector procedure of pressure and velocity field computation. To track the free surface movement with wave breaking, the volume of fluid (VOF) method is implemented. Coupling the VOF and the embedding method, the treatment on free surface problem and complex bottom topography can be easily accomplished. Comparing with the existing experiments, a good agreement is found between numerical results and measured data. 1.
