Patterns of plasma jet arrays in the gas flow field of non-thermal atmospheric pressure plasma jets

Abstract

Schlieren photography, the state-of-art to visualize the invisible flows, has appealed gigantic attention of various researchers in the plasma community. Here, this technique is utilized to address the behavior of the plasma jet arrays in the gas flow field. The goal of this study is to probe the signatures of different parameters and their response in the gas flow field. It is concluded that every parameter exhibits its sensitivity to the plasma in the gas flow field. However, frequency has a significant impact on the reduction of the laminar flow. Furthermore, it is suggested that the flow of the higher momentum region to the lower region is the cause in establishing the instabilities. The compression and rarefaction at the rising and falling edges of the discharge pulses play the dominant role. Plasma jet arrays can be a handy tool for industrial applications unless proper parameters are selected.
