The structure design and hydrodynamic study of the multi-level overtopping wave power device

摘要

To adopt the wave condition of the East China Sea, a new kind of the overtopping wave power device has been designed, and it has a multi-level ramp to capture more wave energy. According to the experimental statistics and the simulation data, the parameters of the structure were confirmed. Then, the simulation experiment was carried out through the Computational Fluid Dynamics (CFD) software. The geometrical model was built by the Computer Aided Design (CAD) software. Analyzing the result of the test, we found the relationship among the wave period, the wave height and the hydraulic efficiency. Obvious improvement of the overtopping discharge was founded when it was compared with the single-level device.
