摘要: 以NREL Phase VI风力机叶片为参照对象,设计一种双层翼叶片。在不同来流风速下,对该新型水平轴风力机叶片气动性能进行数值模拟,对比原始NREL Phase VI风力机在相同来流风速相同叶片高度处的流线图,发现双层翼叶片可较有效抑制流动分离。进一步将双层翼风力机叶片的扭矩值、弯矩值分别与相同条件下NREL Phase VI风力机的结果进行对比,分析双层翼叶片的气动性能以及风能利用率的变化,并研究气动性能随安装角的变化规律。

Abstract: Based on the original blade of NREL Phase VI horizontal-axis wind turbine, a double-wings blade is proposed in this paper. The blade aerodynamic performance of the new horizontal axis wind turbine is numerically simulated under different incoming wind speeds. Firstly, the accuracy and reliability of the simulation method is validated by the traditional NREL Phase VI wind turbine with the experiment results. Secondly, the velocity streamlines at different cross sections along the blade spanwise are studied. The results show that the double-wings blade can suppress the flow separation effectively. Furthermore, the comparisons of torque and bending moment among these double-wings wind turbines under the same condition are made to analyze the aerodynamic performance and the wind energy absorption coefficient. Lastly, the impact of the setting angle of blade on wind turbine performance is considered in this paper.

Key words: wind turbines, flow control, wind power, double-wings
