COMPUTATION OF 3-DIMENSIONAL JET-FLAPPED WING IN VISCOUS-FLOW

In this paper, the problem of three-dimensional jet-flapped wing in vi scous flow is investigated by numerical method. A numerical procedure using the standard k-epsilon turbulence model and the finite volume me thod in general curvilinear coordinates system is applied to solve the steady three-dimensional Navier-Stokes equations. A grid generation s ystem and the PHOENICS code using the SIMPLE scheme were adopted to so lve the N-S equation. Some numerical results were obtained to discuss the effect of the parameters including jet momentum coefficient, jet d eflection angle and aspect ratio of the wing on the performance of the jet-flapped wing.
