Effect of dielectric temperature on Ar atmospheric pressure nonequilibrium plasma jet with different dielectric materials

摘要

In this work, effect of dielectric temperature on atmospheric pressure nonequilibrium plasma jets (APNPJs) with different dielectric materials has been investigated. In our experiments, a single-electrode plasma generation equipped with an AC power supply is applied. Two materials, 95% alumina cerami c and quartz are adopted as dielectric tube. To distinguish the APNPJ status from the argon flow rate, the three modes, laminar, transition and turbulent, are separated.
