摘要：
A numerical method, which is based on Taylor Expansion Boundary Element Method (TEBEM) and linear matching condition for perforated plate, for simulating the hydrodynamic performance of perforated floating bodies is proposed. The accuracy of this method is verified by experimental results. To refine the simulation results, the influence of inertia on the perforated structure is considered. Three types of perforated floating breakwaters are proposed and analyzed. The hydrodynamic performances of these three perforated breakwaters are compared with that of box-type floating breakwater. The numerical results show that installing perforated structures at proper locations can reduce the wave force and motion response while improving the wave elimination ability of floating breakwaters.
