交流峰值电压对大气压表面介质阻挡放电激励器产生的离子风速的影响

Effect on the ionic wind velocity produced by atmospheric surface dielectric barrier discharge actuator under different peak AC voltage

首先介绍了两电极结构表面介质阻挡放电激励器的基本构造和基本工作原理,然后测量了不同峰值电压下激励器所产生的离子风速.实验结果表明在一定的峰值电压范围内,离子风速随着施加的峰值电压的增加而增大,但当电压增加到一定幅值的时候,风速不会有明显的变化,这主要是因为增加的电压主要用于产生流光放电,而不是用来产生离子风.

The basic structure and work principle of atmospheric dielectric barrier discharge two-electrode structure actuator are introduced briefly, and then the ionic wind velocity produced by the actuators is measured under different AC peak-peak voltage.The experimental results show that ionic wind velocity increases with the applied AC voltage in a certain range.However,the wind velocity is nearly invariable when the AC voltage rises above a certain threshold.The reason maybe is the increased voltage mainly used to produce streamer discharge, rather than ionic wind.
