It has been found that by placing a dimple in an aerofoil will reduce drag at a specific AOA. This project work illustrates the change in aerodynamic characteristics of an airfoil by changing the size, shape and location of dimples in an aerofoil. By considering numerous types of dimples, alterations have been done and studied at different Angle of Attacks. Aerodynamic analysis for this airfoil is carried out using Computational Fluid Dynamics. From this investigation it has been detected that the lift force and stall Angle of Attack has been increased efficiently by simply using dimples on the aerofoil.
