SIMULATION OFWAVE BREAKINGBY SPHMETHOD COUPLEDWITH LES TURBULENCEMODELING

In this paper a space-averaged Navier–Stokes approach was deployed to investigate the timedependent wave breaking processes. The developed numerical model is based on the smoothed particle hydrodynamic (SPH) method. SPH is a pure Lagrangian approach which can handle largedeformations of the free surface with high accuracy. In this paper a weakly compressible version ofthe smoothed particle hydrodynamics (WCSPH) method together with a large eddy simulation (LES) approach is used to simulate the wave breaking over a sloping sea wall. The model results were compared with the experimental data and numerical data of Li et al. and demonstrated a good agreement with these results. The model results show that the SPH method provides an accurate way of tracking large deformations of the free surface.
