Study on the effect of bionic flap based on owl wing contour on aerodynamic noise of airfoil
International Journal of Renewable Energy DevelopmentModifying flap geometry to reduce trailing-edge turbulence is an effective approach to lower wind-turbine blade aerodynamic noise. Based on the NACA0018 airfoil, a new bionic serrated flap was designed by mimicking the owl wing structure.
