# 基于Weilbull分布参数的风机翼型气动特性研究Aerodynamic Characteristics Study on Wind Turbine Airfoil Based on Weibull Distribution Function

Abstract: The aerodynamic characteristics of wind turbine airfoil directly influence its efficiency. In this paper, the CFD method was used to study the aerodynamic characteristics of NACA4415 airfoil. The Weibull function method of two-parameter was used to obtain the wind speed probability distribution; the numerical simulation method was established based on Weibull distribution pa-rameters of the airfoil dynamic characteristic; and the airfoil aerodynamic drag, lift and the lift coefficient and drag coefficient were obtained on the 12 degree of attack angle. Then, a method for aerodynamic characteristics of airfoil on the actual wind speed was established based on the Weibull distribution function.
