dcterms:description
This paper focuses on a suppression of the flow separation, which occurs on a deflected flap, by means of vortex generators (VGs). An NACA 63A421 airfoil with a simple flap and vane-type vortex generators wasere 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 different sizes and shapes, along with various spacingsspacing of the vortex generators, were tested. The flow past the airfoil was visualized withthrough two methods, namely tuft filaments technique and oil-flow visualization. The experiments were performed in closed circuit wind tunnels with closed and open test sections. The lift curves for both cases without and with vortex generators were acquired for the determination of the lift coefficient improvement. The improvement was achieved for several cases by means all of all the applied methods.
