Abstract
Wing-In-Surface Effects are studied for two-dimensional wings of three profiles. The profiles are NACA0012 as a standard profile, NACA6409 as a high cambered profile and an S-shaped profile. Numerical simulation is carried out for steady flows past the wings at a high Reynolds number with turbulence by a finite volume method. Results show that for the high cambered profile increase of lift is significant but stability is very poor. The S-shaped profile has good stability and a moderate lift coefficient.
