EFFECT OF VORTEX GENERATORS ON FLOW CONDITIONS OF AIRFOIL WITH DEFLECTED FLAP
Original language description
This paper focuses on a suppression of the flow separation, which occurs on a deflected flap, by means of vortex generators (VGs). An airfoil NACA 63A421 with a simple flap and vane-type vortex generators were used. The investigation was carried out by using experimental and numerical methods. The data from the numerical simulation of the flapped airfoil without VGs control were used for the vortex generator design. Two sizes, two different shapes and various spacing of the vortex generators were tested. The flow past the airfoil was visualized through two methods, namely tuft filaments technique and oil visualization. The experiments were performed in closed circuit wind tunnels with closed and open test sections. The lift curves for both cases with and without vortex generators were acquired for the determination of the lift coefficient improvement. The improvement was achieved for several cases by means all of the applied methods.
