Abstract

Abstract: In this paper, the wing tip jet is proposed to improve the aerodynamic performance of the three-dimensional ONERA M6 wing at high Reynolds numbers. The CFD method is used to perform numerical simulation with the SST k-ω two-equation model. To verify present numerical model, ONERA M6 wing at the attack angle(α) of 2° is selected and the simulation results are in good agreement with the experimental data. The flow around the airfoil at high Reynolds number is simulated at 0°-14° attack angle, and the critical attack angle is 11° without jet. Finally, the influence of the jet on the aerodynamic characteristics of the airfoil at different attack angle are studied and it is found that the lift coefficient and lift-drag ratio of the airfoil increase with jet.
