Title: Investigation on the reaction mechanisms of generation and loss of oxygen-related species in atmospheric-pressure pulsed dielectric barrier discharge in argon/oxygen mixture

Abstract

This work presents a numerical investigation, using a 1-D fluid model, on the generation and loss of oxygen-related species and the spatial-temporal evolutions of the species densities in the atmospheric-pressure pulsed dielectric barrier discharge in the argon/oxygen mixture. The reaction pathways as well as their contributions to the generation and loss of oxygen-related species are given. The considered oxygen-related species include O, O({sup 1}D), O{sub 2}({sup 1}Δ{sub g}), O{sub 3}, O{sup +}, O{sub 2}{sup +}, O{sup −}, O{sub 2}{sup −}, and O{sub 3}{sup −}. The following significant results are obtained. O, O({sup 1}D), O{sub 2}({sup 1}Δ{sub g}), and O{sup −} are produced mainly via the electron impact with O{sub 2}. Ar{sup +} plays an essential role in the generation of O{sup +} and O{sub 2}{sup +}. Almost all of O{sub 3} derives from the reaction O{sub 2} + O{sub 2} + O → O{sub 3} + O{sub 2}. The O{sub 3}-related reactions produce an essential proportion of O{sub 2}{sup −} and O{sub 3}{sup −}. The substantial loss of O{sup −}, O{sub 2}{sup −}, and O{sub 3}{sup −} is induced by their reactions with O{sub 2}{sup +}. Loss of O{sup +}, O, and O({sup 1}D) is mainly due to their reactionsmore » with O{sub 2}, loss of O{sub 2}({sup 1}Δ{sub g}) due to O{sub 2}({sup 1}Δ{sub g}) impacts with O{sub 3} as well as the de-excitation reactions between O{sub 2}({sup 1}Δ{sub g}) and e, O{sub 2}, and O, and loss of O{sub 3} due to the reactions between O{sub 3} and other neutral species. In addition, the densities of O{sup +} and O({sup 1}D) present two obvious peaks at the pulse duration, but the densities of O{sub 2}{sup +}, O, O{sub 2}({sup 1}Δ{sub g}), and O{sub 3} are almost unchanged. The densities of negative oxygen ions increase at the pulse duration and then decline. O{sup −} density is obviously large nearby the dielectric surfaces and the densities of O{sub 2}{sup −} and O{sub 3}{sup −} present generally uniform distributions.« less
