Aerodynamic Performance Study of Wind Turbine Blade for Variable Airfoils

Abstract

We study the variable airfoils (NACA2414, NACA0024, NACA0012 and NACA2424) and compare for aerodynamic performance. XFOIL is used for finding out Lift coefficient, Drag coefficient, Glide ratio (Cl/Cd) and attack angle (α). for finding out the performance of the wind turbine blade we use blade element momentum (BEM) method.
