The Effects Of NACA 0012 Airfoil Modification on Aerodynamic Performance Improvement and Obtaining High Lift Coefficient and Post-Stall Airfoil

In this study, aerodynamic performances of NACA 0012 airfoils with distinct modification are numerically investigated to obtain high lift coefficient and post-stall airfoils. NACA 0012 airfoil is divided into two part thought chord line then suction sides kept fixed and by changing the thickness of the pressure side new types of airfoil are created. Numerical experiments are then conducted by varying thickness of NACA 0012 from lower surface and different relative thicknesses asymmetrical airfoils are modified and NACA 0012-10, 0012-08, 0012-07, 0012-06, 0012-04, 001203, 0012-02, 0012-01 are created and simulated by using COMSOL software.
