Abstract: The aim of this study is to modify, by using surface plasma actuators, the laminar-to-turbulent transition location of a Blasius boundary layer developing on a flat plate mounted in an opened wind tunnel. Measurements of flow velocities were performed by hot wire anemometry. Results show that an actuator placed upstream the natural transition zone enables the promotion or the delay of the transition onset, depending on the location, the voltage amplitude, and the frequency of the high voltage electrical parameters.
