Description
Summary:Enhancing discharge energy in dielectric barrier discharge (DBD) is vital for various applications. This study establishes a theoretical formula for predicting enhanced discharge in multi‐needle‐plate (MP) DBD, accounting for factors like needle count, rotation speed, and voltage frequency. Experiments validate the formula's accuracy, showing that precisely matched parameters result in enhanced discharge power, heightened streamer luminosity, and curved streamer channels. Lissajous figures in MP DBD exhibit elliptical shapes due to residual discharges during voltage fall. Statistical analysis of current pulses and discharge images confirms that dielectric plate rotation increases discharges and extends their duration during voltage fall. Numerical simulations highlight surface charge movement's role in enhancing the electric field and affecting streamer propagation direction in the air gap. This study formulates a predictive formula for enhanced discharge in multi‐needle‐plate dielectric barrier discharge, and experiments verify that precise parameter matching improves discharge power and streamer luminosity and induces curved channels. Numerical simulations emphasize the role of surface charge movement in enhancing the electric field and affecting streamer propagation.
