Effect of Stall Strip Position, Size and Geometry on the Lift Coefficient of NACA 001 Aerofoil

Effect of Stall Strip Position, Size and Geometry on the Lift Coefficient of NACA 001 Aerofoil

This study aims to determine the optimum position and geometry of stall strips (SS) to control sudden fall of lift in wind turbine blades. The type of airfoil used in this study is NACA 0015 with 150 mm of chord length. Total of five positions, two geometries and three sizes of SS configurations are...
