Abstract

Abstract: The aerodynamic characteristics of an airfoil with a jet issuing from its lower surface are investigated by numerical method.The Navier-Stokes equations are solved using Beam-Warming scheme,By the numerical experiment of different jet parameters,some important characteristics are obtained.Jet can increase the lift of an。airfoil within some range of jet velocity,but beyond this velocity range the lift decrease,with jet location near to the trailing edge of the airfoil,the increase lift effect of jet is more efficient.The lift does not depend on the variation of jet pressure closely.

Key words: jet flow, lift augmentation, numerical analysis
