Abstract :We numerically investigated NACA 0018 airfoil with slot at various angles of attack. The computational fluid dynamics (CFD) results were compared with the base airfoil to show the effectiveness of the airfoil. Reynolds number was kept constant as Re=3x105 to thoroughly understand how different locations of slot would provide passive flow control from aerodynamic perspective. We have used three different slot locations to reveal the effectiveness of the slot compared to the base airfoil for higher angles of attack. Our results show that the slotted design would yield to increase the lift and to delay the stall angle of base airfoil.
