Influence of Oxygen Impurity on Nitrogen Atmospheric-Pressure Plasma Jet

This study discussed the effect of oxygen impurity in inlet gas a nitrogen atmospheric pressure plasma jet (APPJ). A numerical model that takes into account fluid dynamics, heat transfer, mass diffusion, and chemical reactions was developed to simulate APPJ. Further, DC APPJ experiment performed verify temperature characteristics on treated surface. The decreased with an increase impurity. Moreover, influenced related excited neutral species. Specifically, added impurity, N-related species whereas O- NOx-related increased. Because state constitutes most important reactant treatment, this could serve as reference for adjustment
