摘要

提高介质阻挡放电(DBD)中的放电能量对于各种应用都是至关重要的。考虑针数、转速和电压频率等因素，建立了预测多针板(MP) DBD中放电增强的理论公式。实验验证了公式的准确性，表明精确匹配的参数可以提高放电功率，提高流光亮度，并使流光通道弯曲。由于电压下降时的残余放电，MP DBD中的利萨图呈现椭圆形状。电流脉冲和放电图像的统计分析证实，介质板旋转增加了放电，并延长了电压下降时放电的持续时间。数值模拟突出了表面电荷运动对电场的增强作用和对流光在气隙中的传播方向的影响。

Influence of rotating dielectric barrier on discharge characteristics in multi-needle-plate DBD

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.
