| 中文摘要: |
| 基于线性势流理论，应用匹配特征函数方法求解近岸反射条件下波浪与非对称波能浮子-防波堤系统相互作用的绕射和辐射问题，通过Haskind关系验证了所构建半解析模型的正确性。应用该模型研究了浮子形状、防波堤与岸线间距和波浪入射角度等主控参数对反射系数、俘能效率等的影响规律。计算结果表明：对于孤立浮子而言，非对称浮子的俘能效率明显优于对称型浮子；防波堤的存在对浮子的俘能效率有明显的改变，主要体现为俘能效率曲线在特定频率区间出现接近零的现象，且呈现双峰趋势；岸线反射对集成系统的水动力性能影响较大，主要体现为浮子和防波堤的水动力系数及俘能效率随岸线与防波堤间距的变化呈现周期性变化（周期约为kD2=π）。 |

| Based on linear potential flow theory, the matching eigenfunction method is employed to solve the diffraction and radiation problems of wave interaction with an asymmetric wave energy buoy-breakwater system under coastal reflection conditions. The semi-analytical model is validated using the Haskind relation. The effects of key parameters—including buoy shape, shoreline-breakwater spacing, and wave incident angle—on the reflection coefficient and energy extraction efficiency are investigated. The results indicate that, for isolated cases, asymmetric buoys exhibit significantly higher energy extraction efficiency than symmetric ones. The presence of the breakwater markedly alters the energy extraction efficiency of the buoy, especially in frequency ranges where the energy extraction efficiency approaches zero and a bimodal trend is observed. Shoreline reflection has a substantial influence on the hydrodynamic performance of the integrated system, leading to periodic variations in hydrodynamic coefficients and energy extraction efficiency with respect to shoreline-breakwater spacing (with a period of approximately kD2=π). |
