Numerical Simulation of Wave Overtopping of Breakwater Armored with Porous Layers and Water-Structure Impaction
A numerical model has been developed to study wave overtopping of permeable units protected breakwater and water-structure impactions.The numerical model solves the Reynolds Averaged Navier-Stokes equations outside of porous media and solves the spatially averaged Navier-Stokes equations in porous media, respectively.The numerical model is first validated by experimental data.The validated model is then employed to investigate the breaking wave overtopping porous media protected breakwater.The overtopping discharge and impact forces on the structures behind the crown wall in different wave conditions are studied.The increase of wave height brings increasing maximum overtopping discharges and different spatial distribution of water behind the crown wall.The impact forces on the structures are determined by both incident wave height and relative positions of the structures.
