Effect of a plasma actuator on an airflow along an inclined wall: P.I.V. and wall pressure measurements

In this work, we propose to analyse experimentally the ability of a DC surface corona discharge to modify an airflow along an inclined wall. The goal is to fully detach an airflow which is naturally attached along the inclined wall. Two sets of experiments conducted in a wind tunnel up to 10 m/s have been done. First, pressure measurements along the inclined wall have shown a decrease of the pressure downstream the discharge. Next, P.I.V. measurements have shown that the discharge induces a velocity decrease along the inclined wall. Both results are characteristics of a detached airflow.
