感应和叶片弹性建模对风力涡轮机转子性能预测的影响
本研究探讨了叶片感应建模对风力涡轮机转子气动弹性预测精度的影响。它扩展了 AEOLIAN(AErOeLastic sImulAtioN)的功能,AEOLIAN 是一种基于叶片元素动量理论(BEMT)的流体结构相互作用(FSI)求解器,采用块状质量方法来表示叶片结构。在这里,AEOLIAN 的分析型尾流感应工程模型被 AeroROTOR 最初采用的物理上一致的三维自由涡流(FVW)计算结果所取代。这一多功能气动弹性仿真工具是在 MATLAB Simulink/Simscape-Multibody© 框架内实现的,该框架是一个模块化环境,适用于关注风力涡轮机气动伺服弹性应用的行业分析师、研究人员和学术用户。此外,它还为开发先进的兆瓦级转子控制法奠定了基础,促进了下一代风力涡轮机设计和优化的创新。本文的分析重点是预测底部固定的 NREL 5 兆瓦转子在工作范围内均匀轴向流的气动弹性行为,并在有/无风偏差(偏航)的流入额定条件下进行更详细的研究。通过与现有计算流体动力学 (CFD) 和与计算流体动力学 (CFD) 相结合的计算结构动力学 (CSD) 的高保真数据进行比较,对关键性能参数进行了研究。
