An experimental study is carried out to investigate the influence of dielectric barrier discharge (DBD) plasma actuator on flow around a NACA 0015 airfoil at Re = 5x104. DBD plasma actuator starting at x/C = 0.1 is mounted to NACA 0015 airfoil at chord direction to increase lift coefficient (CL) and postpone stall. Measurements are performed at the actuator angle of = 0, 30, 60 and 90. Lift force measurement is implemented by using the load cell between = 0 and 15. The results indicated that stall angle is postponed from 9 to 11 and CL is significantly improved at post-stall region.
