叶片作为风力发电机最关键的部件,其气动特性好坏对于风力发电至关重要。以750 kW风力机叶片为例,采用Wilson设计方法对叶片进行设计。在此基础上,应用流体计算软件CFD对所选翼型进行气动分析,得出翼型表面压力随攻角变化关系。该方法可提高风力机叶片等复杂曲面的建模效率并可对叶片后续的气动性能分析奠定基础。

As the most important part of wind turbine,the aerodynamic properties of blade have crucial influence on wind power generation.In this paper,the blade of 750 kW wind turbine is designed through Wilson method.Based on the de-sign,an analysis with the aerodynamic properties of the sample wing profile is carried out with the liquid computing software CFD,and how the wing profile’s surface pressure changes as the angle of attack changes is also found out.With this meth-od,the modeling efficiency of blade’s complex surfaces can be improved,and the subsequent aerodynamic analysis of the blade can be conducted based on this model.
