小型垂直轴风力发电机风轮效率的试验研究

Experimental Study on Efficiency of Wind Wheel in Mini-VAWT

以提高效率为目的,对影响垂直轴风力发电机风轮效率的叶片曲率、数量及安装角进行了理论分析与试验研究,试验结果证明了理论分析的合理性。给出了采用弧形叶片、30°安装角及叶片数量为12时风轮效率较高的明确结论,为今后的深入研究打下了良好的基础。

To improve the efficiency of the wind wheel, the factors including the curvature, number and the setting angle of the blades which influenced the efficiency of the wind wheel were studied. It is proved that the theoretical analysis is reasonable. Based on the analysis, we draw a clear conclusion that the efficiency of the wind wheel will be higher when the blade is bent with the number of 12 and the setting angle is 30,which lays a good foundation for the further research.
