摘要：
The oscillating wave surge converter (OWSC) consists of a flap, a hinge, a base and a power output system that use extracts energy from the waves and use converts it into electrical energy. In this paper, two configurations of OWSC devices are numerically investigated using a smoothed particle hydrodynamic approach. The cylindrical and rectangular flap OWSC are compared, and the effects of four parameters (wave height, wave period, water depth, and power take-off damping) are investigated. The calculation results show that the change of any parameter mentioned above will lead to the change of OWSC's time-averaged power, and a nonlinear functional relationship is shown between them. The variation of the capture factor with different working conditions is investigated simultaneously, and the relationship between the capture factor and the wave parameters is considered to be dissimilar when the water depth varies. An explicit function is proposed to describe the relationship between time-averaged power of OWSC and wave period, wave height, water depth and power take-off damping, and the accuracy of the function is verified well by several cases.
