Abstract:

This article aims to analyze the effect of vortex generators (VGs) placed on symmetrical and cambered aerofoil. Simulation and experimental works were carried out using NACA 6321 and NACA 0021 aerofoils at different angles of attack (AOA) and aerodynamic performance obtained at a velocity of 15 m/s and 140625 Reynolds number (Re). In this study, aerofoils with the same thickness and a novel design of minute VGs were introduced and placed at a location of 0.5C (50% of chord). The VGs improved the stall AOA by 4° and 2° in simulation and experimental methods, respectively, with no drag increment compared to the baseline aerofoil. These VGs controlled the boundary layer over an aerofoil with enhancement in aerodynamic efficiency of subsonic aircrafts.
