外文摘要：A wave dissipating and defending system consisting of a submerged curved wing-like structure and a vertical wall is proposed. The interactions between the wave and the systems with a submerged rectangular structure and a submerged curved wing-like structure before a vertical wall are comparatively studied using a numerical wave flume based on OpenFOAM. The wave reflection coefficients of the two systems are calculated under different wave periods. The distributions of the flow field and vortex viscosity field are analyzed, and the main mechanism of wave dissipation is discussed. The numerical results indicate that the wave dissipating performance of the wave dissipating and defending system with a curved wing-like submerged structure is better than that of the system with a rectangular submerged structure.
