In the present study, the problems of diffraction and radiation of water waves by a cylindrical heaving wave energy converter (WEC) placed in front of a reflecting V-shaped vertical breakwater are formulated. The idea conceived is based on the possible exploitation of amplified scattered and reflected wave potentials originating from the presence of V-shaped breakwater, towards increasing the WEC’s wave power absorption due to the wave reflections. An analytical solution based on the method of images is developed in the context of linear water wave theory, taking into account the hydrodynamic interaction phenomena between the converter and the vertical wall. Numerical results are presented and discussed concerning the hydrodynamic forces on the absorber and its wave power efficiency for various examined parameters, namely, the breakwaters’ forming angle, the distance between the converter and the vertical walls and the wave heading angle. The results show that the amount of the harvested wave power by the WEC in front of the walls is amplified compared to the wave power absorbed by the same WEC in the open sea.

无限长的底部安装的 V 形防波堤前的波浪吸收器对水波的衍射和辐射

在本研究中，提出了放置在反射 V 形垂直防波堤前的圆柱形升波能量转换器 (WEC) 对水波的衍射和辐射问题。构想的想法基于可能利用源自 V 形防波堤的放大散射和反射波势，以增加 WEC 由于波反射而吸收的波功率。在线性水波理论的背景下，考虑到转换器和垂直壁之间的水动力相互作用现象，开发了基于图像方法的解析解。给出并讨论了关于吸收器上的水动力及其各种检查参数的波浪功率效率的数值结果，即，防波堤的形成角、转换器与垂直壁之间的距离和波浪航向角。结果表明，与外海中相同 WEC 吸收的波浪功率相比，墙前 WEC 收集的波浪功率量被放大。
