摘要: ABSTRACT

This paper investigates wave reflection characteristics induced by a piston-type porous (PTP) wave energy converter, consisting of a solid wall, a vertical porous plate, a transmission bar, a rigid block constrained by rollers, a spring and a damper. The work also researches the force exerted on the porous plate and the response of the PTP wave energy converter. This study subjects the wave energy converter to a dynamic loading external source from the wave attack and uses a mathematical model with a single degree of freedom (SDOF) system to simulate the dynamic system. A linear wave theory governs the whole fluid domain, divided into two regions by the vertical porous plate. Darcy’s law is also applied in the porous plate. Finally, this investigation employs eigenfunction expansion to obtain the solution. The current study conducts a series of numerical experiments, including the reflection coefficient, the added-mass coefficient, wave force acting on the porous plate, and converter responses.
