摘　　要：作为风力机气动设计和运行优化的重要基础之一,风力机翼型气动性能分析的应用日益广泛。采用NUMECA数值模拟软件对风力机NACA4412翼型(弯度为4%)进行气动模拟分析,模拟结果与实验数据较为一致。在此基础上,对NACA2412、NACA4412、NACA6412 3种不同弯度翼型的升阻力系数、升阻比和其在攻角为8°和14°时的绕流情况进行模拟分析,发现相对于弯度较大的翼型,弯度较小的翼型更适宜运行在大攻角下。As one of the most important foundations of wind turbine aerodynamic design and optimum operation,the aerodynamic performance analysis of wind turbine airfoil is widely used.This paper makes the simulation of the aerodynamic performance of airfoil NACA4412 with relative camber of 4%by using NUMECA software,and the results are accordant with the experimental data.Based on which,the paper simulates and analyzes the aerodynamic performance of three airfoil of NACA2412,NACA4412 and NACA6412 with different lift drag coefficient and lift-drag ratio,as well as the flow condition at the attack angle of 8°and 14°.The simulation shows that the airfoil with small camber is more suitable for running at a higher attack angle than that of larger curvature.
