摘　　要：选取NACA4412,NACA4418,FFA-W3-211,FFA-W3-360,FX60-126和NREL-S809等6种常用风力机叶片翼型,进行二维几何建模和计算域网格划分,运用FLUENT软件对风力机叶片翼型的空气动力性能进行数值模拟和仿真分析;并与实验数据进行参照、对比和分析,验证数值模拟的可靠性。对风力机叶片常用翼型进行气动数值模拟计算和分析,可深化了解风力机翼型的气动性能,为风力机叶片翼型选型和叶片翼型改型设计和研发工作提供技术参数和指导意见。The blades and the rotors are the key equipments for catching wind power in wind turbine generator. The calculated models of six kinds of aerofoil of blades were built. The blades are NACA4412, NACA4418, FFA-W3-211, FFA-W3-360, FX60-126 and NREL-S809. With the help of FLUENT software, the aerodynamic performance of 2D aerofoil of wind turbine blade were simulat- ed and analyzed. Comparison between the simulated data and the experiment data has been carried out in order to verify the feasibility and the reliability of aerodynamic numerical simulation of wind turbine. The simulation and analyses is helpful to understand the aerodynamic performance and character of aerofoil of wind turbine, and supply technological parameters and advices for the design and research of blade aerofoil.
