摘要：
The present paper deals with the investigation of the efficiency of an oscillating water column device placed in front of a reflecting vertical breakwater. At a first stage, the exciting forces and moments acting on the OWC along with the motion- and pressure-dependent hydrodynamic characteristics of the device, placed in front of a vertical wall, are derived by the solution of the diffraction, motion- and pressure-radiation problems supplemented by representative numerical results concerning the air pressure inside the oscillating chamber. Hydrodynamic interactions between the float and the adjacent breakwater are exactly taken into account using the methods of images. The second part of the paper is devoted to the geometric parametric analysis concerning the distance between the OWC device and the breakwater and the angle of wave propagation to examine how the presence of the vertical wall affects the efficiency of the wave energy device.
