Abstract: The effect of wavelength and amplitude of a sinusoidal wavy ground on the aerodynamics and flowfield of a NACA 0012 airfoil at low Reynolds numbers was investigated experimentally. The results show that, regardless of wave ...

Abstract: The impact of ground proximity on the aerodynamics and trailing vortices of an inverted delta wing was investigated experimentally. The ground proximity always led to a lift and drag increase compared to their outside ...
