  Abstract: Computational investigation carried out to the effects of a two-dimensional roughness element placed on the suction surface of a zero camber airfoil of 1 m chord on its performance is presented. The roughness element was placed on suction surface of the airfoil at a distance of 30% from the leading edge of the airfoil. The roughness element was in the form of a wire. The diameter of the wire was …
