This paper is focused on an influence of vane type vortex generators on flow behaviour. A model of NACA 63A421 airfoil with a simple flap was used. Two sizes, two different shapes, two positions from separation location and various spacing of the vortex generators were tested. The investigation was performed using three different visualization methods and pressure distribution measurements in closed circuit wind tunnels with closed and open test sections at Reynolds number 200 000. The improvement was achieved for several cases by means all of the applied methods.
