摘　　要：采用CFD方法对1.5 MW风力机叶片DF77A和DF77D进行三维定常数值模拟。分别与风力机设计功率数据进行对比,在确认数值计算结果可信的基础上,对比了两种叶片三维粘性流场的流动细节,分析了两种叶片在不同来流风速条件下气动性能,同时详细分析了两种叶片对1.5MW机组机舱尾部测风仪的影响,为大型兆瓦级风力机优化设计提供参考。The blade DF77A and DF77D of 1.5MW wind turbine are carried out 3D steady numerical simulation by CFD method. The computation results have been compared with the design power curve and shown the same tendency as the design value. Based on the numerical results, the 3D viscous flow filed of two kinds of blades are compared, and the aerodynamic performance of the blades are analyzed under the different wind speed. While the effect of the blades to anemometer on nacelle tail are analyzed in detail as well. The study will offer design reference for large MW wind turbine.
