Abstract The positive effects of a split on the aerodynamic performance of fixed wings are well known. However, for horizontal axis wind turbines (HAWTs), changes in the local angle of attack (AoA) and relative velocities along the blade create complex three-dimensional flow over blades, making the analysis of the split location very challenging. In this paper, the effects of the radial position of a split are investigated using CFD simulations of five different split versions of the NREL Phase VI blade and the original blade. The CFD models are solved as transient simulations at different tip speed ratios (TSRs). Results demonstrate that the power generated by all of the split blades at any TSR

使用分裂叶片的水平轴风力涡轮机叶片的发电增强

摘要 分裂对固定翼气动性能的积极影响是众所周知的。然而，对于水平轴风力涡轮机 (HAWT)，局部攻角 (AoA) 和沿叶片的相对速度的变化会在叶片上产生复杂的三维流动，这使得对分裂位置的分析非常具有挑战性。在本文中，使用 NREL 第 VI 阶段叶片和原始叶片的五种不同分割版本的 CFD 模拟，研究了分割径向位置的影响。CFD 模型作为不同叶尖速比 (TSR) 下的瞬态仿真进行求解。结果表明，在任何 TSR 下，所有分体式叶片产生的功率
