Abstract

The electrical characteristics of a dielectric barrier discharge (DBD) symmetrical actuator at low pressures gave been investigated. A power source–actuator–DBD system has been analyzed. The plot of the feed voltage frequency at which a voltage resonance is observed at the outer electrodes of an actuator with a given configuration against air pressure has been constructed. The DBD density, as well as the capacitance and Q factor of the system, as a function of pressure in a pressure chamber, has been determined. It has been found that, as the pressure drops, the fraction of the DBD energy spent on generating a synthetic jet grows.

低压介质阻挡放电的共振特性

摘要

研究了低压下电介质阻挡放电（DBD）对称致动器的电气特性。已分析了电源-执行器-DBD系统。已经构造了馈电电压频率的曲线图，在该曲线图中在具有给定配置的致动器的外电极上观察到电压谐振，以抵抗气压。已经确定了DBD密度以及系统的电容和Q因子与压力室中压力的关系。已经发现，随着压力下降，用于产生合成射流的DBD能量的比例增加。
