Abstract :
Overtopping Wave Energy Convertor (OWEC) is an offshore wave energy convertor, which comprises the circular ramp and reservoir. It collects the overtopping waves and converting water pressure head into electric power through the hydro turbines installed in the vertical duct, which is fixed in the sea bed. The performance of OWEC can be represented by the operating water heads of the device, which depend on the amount of the wave water overtopping into the reservoir. In the present paper, the reservoir with the duct connecting to the sea water is studied in the experimental wave tank. Both the overtopping motion and discharges of the reservoir are investigated together, and several shape parameters and incident wave conditions are investigated to demonstrate their effects on the performance of OWEC.
