Effect of gas injection mixing on reactive species transport in an atmospheric pressure cold plasma jet

Atmospheric pressure cold plasma jets have been focused on their potential applications to material processing and medical use. For the extensive use of plasma jets, it is essential to generate and transport abundant reactive species. But the amount of additive gas is limited because it easily reduces plasma density and temperature. In this reason, effective gas mixing and injection is necessary. This work aims to point out that selection of gas injection and mixing methods is a critical factor to generate and transport reactive species effectively in a plasma jet.
