Abstract

Abstract:

Numerical results are presented by simulating the separated flow around a WIG craft in flight close to ground at a high incidence angle. The Farve-averaged N-S equation of steady compressible flow and the standard k-epsilon turbulence model are solved by Fluent software. The effect of flight height on the separated flow around wings of WIG craft is provided. Why flow separates at lower flight height is explained. The influence of the separated flow on aerodynamics of WIG craft is analyzed in detail.
