Ionic wind generation through coplanar discharge: A plasma actuator without exposed electrodes

This study demonstrates the successful induction of a unidirectional ionic wind by adding an embedded electrode in coplanar discharge, thus breaking generation symmetrical electric field. The strategy for is based on separating ionization process and charged-particle acceleration process. Conventional plasma actuators used to induce typically incorporate exposed electrodes that pose risk unexpected airflow disturbance reduce durability due oxidation. However, discharge-based, exposed-electrodeless actuator developed this overcomes these issues. discharge generates diffused uniform surface desirable attribute actuators. velocity generated comparable conventional when applying square-waveform bias voltage additional electrode. Furthermore, emphasizes significance phase difference between repetitive pulses generating accelerating charged particles.
