Effect of Vortex Generators on Airfoil NACA 632-415 to Aerodynamic Characteristics Using CFD

open access: yesInternational Journal of Electrical, Energy and Power System Engineering, 2023
To determine the aircraft’s flight performance, the airfoil type must be considered when designing the wing. A vortex can form when the airfoil travels through a fluid stream with a difference in velocity and pressure around it.
