Abstract
Potential flow models employing the jet-flap theory are inadequate for simulating the flowfield around an airfoil in ground effect with a jet issuing from its undersurface. Euler equations serve as a better physical model because they do not require the assumption of an infinite open wake behind the jet with pressure equal to the free-stream pressure. Euler equations can also capture the vortex formation behind the jet and most of the airfoil/jet/ground-plane interaction, except the effect of entrainment. In this paper, airfoil/ jet/ground-interaction flowfields are calculated by solving Euler equations on body-conforming curvilinear grids.
