摘要：

A mathematical model for a flap-type wave energy converter is derived in the framework of a linear inviscid potential flow theory. The wave field resulting from the interaction of an incident plane wave with the flap is determined by applying Green's integral theorem to the fluid domain. The hydrodynamic parameters of the system are determined, allowing to solve the equation of motion of the flap and to obtain the capture factor of the device. Asymptotic analysis in the far field yields new relations between the hydrodynamic parameters of the system, which reveal the peculiarity of a flap-type device with respect to traditional point-absorber converters. Finally, comparison is made between the behaviour of the device in the open ocean and in a channel. It is shown that the effect of the channel lateral walls on the system can concur to increase its performance.
