Near-trapping对WEC阵列装置提取功率的影响

论文摘要

Near-trapping现象是在特定入射波频率下规则阵列结构中发生的一种水动力强相互作用现象。为了探究neartrapping现象对阵列波浪能装置（WEC）提取功率的影响,本工作基于线性势流理论,采用高阶边界元法,针对由圆柱形垂荡浮子组成的点吸收阵列WEC,研究near-trapping现象对等间距线型阵列结构的水动力相互作用和功率提取特性的影响。研究发现:near-trapping的发生取决于浮子间距与波长的比值和入射波方向角;near-trapping会大大降低WEC阵列提取的功率;无论是否发生near-trapping现象,沿入射波方向WEC数量都不宜过多,遮蔽效应会减少阵列提取的总功率。
