Abstract

海上风−浪−流的存在使得海上风力机平台会产生六个自由度方向的运动。为研究纵摇运动对海上风力机 尾流特性的影响,基于 OpenFOAM 平台,采用 RANS 方法的 k-ε 模型和重叠网格技术,考虑风剪切来流和简化的 漂浮式平台六自由度运动条件,对纵摇状态下的风力机尾流进行数值研究。研究结果表明,纵摇工况下的风力机尾 流恢复速度更快,且尾流恢复速度会随着纵摇运动的频率和幅值增加而增加。当纵摇运动的振幅较小时,近场尾流 的风速恢复会受到一定的影响,而对远场尾流影响不大;当振幅较大时,纵摇运动会加速全部尾流区域的风速恢复, 并出现更为明显的扩散现象。研究结果对揭示漂浮式海上风电机组纵摇运动下尾流产生和扩散的机理有一定的意 义,为完善漂浮式海上风电场尾流损失模型提供了一定的物理基础。
