Pneumatic Characteristic Property Studies Of Blade Airfoil Profile For Horizontal Axis Wind Turbine

Horizontal axis wind turbine is the most effective application of wind power installations. To improve the efficiency of wind energy usage in the wind turbine and shorten the development cycle leaves, this paper first using Computational Fluid Dynamics software—FLUENT to numerically simulate the more traditional horizontal axis wind turbine NACA63-215; Come to the aerodynamic characteristics of the airfoil; Airfoil and geometric parameters, the aerodynamic performance of the Mach number and Reynolds; Then calculated lift and drag characteristics by adding 45°trailing edge flap airfoil and Gurney trailing edge. The simulation results show that adding in the tail-wind 45°trailing edge flap and the wing Gurney flap have been able to raise the maximum lift coefficient and efficient airfoil lift coefficient; For Gurney flap run,the increasing effectiveness is Closely associated with height. The results show, adding flap is a convenient and effective method for wind turbine wind-oriented wing.
