The following study focuses on the simulation of self-actuated flaps used on the upper surface of the wing for flow separation control. Previous studied have shown the effectiveness of such flaps for flow separation control. The simulation was performed on a rectangular section of standard NACA 4412 Airfoil with flaps(self-actuated) attached on the upper surface of the airfoil. The different configurations of the flaps were simulated. The effect of such self-actuated flaps on the aerodynamics of the wing section such as lift and drag was studied. The simulations were conducted on ANSYS-Workbench 16.
