چکیده

In this paper a space-averaged Navier–Stokes approach was deployed to simulate the wave propagation over coastal structures. The developed model is based on the smoothed particle hydrodynamic (SPH) method which is a pure Lagrangian approach and can handle large deformations of the free surface with high accuracy. In this study, the large eddy simulation (LES) turbulent model was coupled with the weakly compressible version of the smoothed particle hydrodynamics (WCSPH) method to simulate the wave propagation over coastal structures. The WCSPH model was employed to simulate the periodic wave propagation over impermeable trapezoidal sea wall and submerged breakwater. The numerical model results were validated against the experimental and numerical data found in the literatures and some relatively good agreements were observed. Afterwards, solitary wave propagation over impermeable trapezoidal sea wall on a sloped bed was carried out and the results of numerical simulations were compared both qualitatively and quantitatively with experimental data of Hsiao and Lin (2010). The results of this study show that WCSPH method provides a useful tool to investigate the wave propagation over coastal structures.
