Numerical and experimental research for wave damping over a submerged porous breakwater

In this paper, wave motion coupled with porous flow within a submerged porous breakwater is studied. Based on Volume-of-Fluid (VOF) technique a Synchro-Linking method (SLM) is developed to simulate waves and porous flow, which are respectively governed by Navier-Stokes' and Forchheimer's equations. Dynamic pressure inside the porous breakwater and wave dissipation over it are obtained through calculation. It is discovered that both the results are significantly affected by breakwater dimensions, as well as the parameters of incident waves. Experiments are also carried out to verify numerical models and results. Comparison between them shows good agreement.
