Abstract:In this paper,a novel π-shaped plate-type permeable breakwater with wave baffles arranged on the arc plate was proposed to improve the wave dissipation performance.The numerical model sol-ving the wave-breakwater interaction was established based on OpenFOAM and validated using experi-mental results.The effects of relative submergence depth,relative wave height,relative height of wave baffles,and relative width of plate on the wave dissipation performance of the proposed breakwater were studied numerically.The results showed that the transmission coefficient decreased with increas-ing relative width of plate and relative height of wave baffles,and increased with increasing relative submergence depth.The reflection coefficient presented the opposite trend with the transmission coeffi-cient.The amplitudes of decrement of transmission coefficient and increment of reflection coefficient both decreased with increasing relative height of wave baffles.The results of this paper provide valua-ble information and significant guidance for designing an effective permeable breakwater in practical en-gineering application.
