中文摘要：准陷波效应会显著放大柱群间的波浪振幅与结构载荷,严重威胁海洋风机基础及海洋平台的安全与稳定性。基于二维频域势流理证有限元模型,在波浪入射角为0°、30°和90°的条件下对呈等边三角形排列的等直径三圆柱群的准陷波特性及其波浪荷载响应展开系统数值分析。计算结果表明:在三种入射角度下圆柱所受水平波浪均高于垂直波浪载荷;当波浪入射角为30°时,结构承受的波浪荷载达到峰值;除0°入射角工况外圆柱水平波浪载荷外,其余工况下圆柱所受波浪载荷的峰值频率均随直径与柱间距比a/d减小向高频方向移动。研究成果为优化波浪能俘获装置的布置策略及海洋平台防护结构设计提供了重要理论依据。

外文摘要：The near-trapping phenomenon can significantly amplify wave amplitudes and structural loads between cylinder groups,seriously threatening the safety and stability of offshore wind turbine foundations and marine platforms.Based on a two-dimensional frequency-domain potential flow finite element model,this study systematically analysed the near-trapping characteristics and wave load responses of an equilateral triangular array of three cylinders of equal diameter under wave incidence angles of 0°,30°,and 90°.The results indicate that under all three incidence angles,the horizontal wave forces on the cylinders are greater than the vertical wave forces.The wave-induced load on the structure peaks when the wave incidence angle is 30°.Except for the horizontal wave force on the cylinders at a 0°incidence angle,the peak frequencies of the wave forces in all other cases shift toward higher frequencies as the ratio of diameter to cylinder spacing(a/d)decreases.These findings provide an important theoretical basis for optimizing the layout of wave energy capture devices and the protective design of marine platforms.
