Implication

Experimental study reveals that square waveforms maximize body force in dielectric barrier discharge plasma actuators, indicating distinct trade-offs for plasma-assisted flow control.

Key Points

To assess how different electric waveforms driving a dielectric barrier discharge plasma actuator affect electrical properties, plasma morphology, and airflow generation.
Tested various alternating current supply waveforms driving a surface dielectric barrier discharge plasma actuator.
Measured electrical parameters, discharge structure, body force generation, and two-component time-resolved electric wind velocities across single signal cycles.
Square waveforms yield optimal body force production and higher mean electric wind velocities compared to alternative waveforms.
Sinusoidal waveforms produce greater airflow velocity fluctuations throughout the cycle.
Time-resolved velocity data show that the electromechanical conversion mechanism operates quasi-linearly in the vicinity of the discharge.
