Two-Dimensional Modeling of the Active Species Flow Generated by an Atmospheric Plasma Jet

A proper description of the flux of active species generated by cold atmospheric-pressure (AP) plasma jets is of crucial importance for plasma applications. To that end, a 2-D fluid model has been constructed to investigate the effect of the coupling between the plasma kinetics and plasma flow. It is shown that pure-argon cold AP RF plasma jets are not only controlled by diffusion losses but also by convective transport of argon molecular ions Ar
