英文摘要: Ocean wave energy is clean and renewable. Exploitation of wave energy increases energy supply, improves ecological environment, enhances the capacity of marine resource extraction, serves island residents and border military troops. Hydrodynamic study and optimum design of a wave energy convertor (WEC) are the keys to increasing the efficiency of wave energy exploitation. This project will, through extensive study on the hydrodynamic performance, to optimize the design of a newly developed bottom-hinged flap WEC. The new WEC was put forward in the consideration of wind-wave dominated and typhoon-frequent- occurring sea-states of China. The performance of the WEC will be investigated through the combination of theoretical analysis, numerical simulation and physical model tests. An accurate and efficient fully-nonlinear time-domain numerical model will be developed for analyzing the flap WEC. Large scale water flume and water tank model tests will be conducted to investigate the influence of the near-shore topography, the tidal current and the variation of wave spectrum on the hydrodynamic performance of the WEC. The compound form method, which is a mechanical optimization method, will be implemented into the optimum hydrodynamics design of the bottom-hinged flap. The project is of great importance in the hydrod
