Aerodynamic noise characteristics of airfoils with morphed trailing edges
International Journal of Heat and Fluid Flow, 2022 Numerical investigation of the aerodynamic and aeroacoustic characteristics of a symmetrical NACA 0012 airfoil developed by National Advisory Committee for Aeronautics (NACA) with a conventional hinged flap and a morphed flap has been carried out. The unsteady flow characteristics over the airfoil surface and at the airfoil wake are captured using high-

Acoustic and flow characteristics of an airfoil fitted with morphed trailing edges [PDF]
Experimental Thermal and Fluid Science, 2021 Abstract An experimental study of a simple NACA 0012 airfoil fitted with two different flap profiles was carried out to characterize their aerodynamic and aeroacoustic performance. The airfoil with a flap deflection angle of β = 10° was tested for a wide range of angles of attack at a chord-based Reynolds number of Re c = 2.6 × 10
