大气压氩等离子体射流特性
Characteristics of the Atmospheric Pressure Argon Plasma Jet
摘要
Abstract
Abstract: In order to produce uniform, steady and large volume dielectric barrier discharge (DBD) argon plasma jets at atmospheric pressure, a plasma generator with a screw-like inner electrode configuration was proposed. A uni- form, steady and visibly glow-like discharge plasma jet was obtained at an open environment using this newly-de- signed plasma generator. The experimental and preliminary zero- dimensional modeling results show that, the dis- charges can be operated at an initial, transitional, stable or unstable discharge modes with the increase of the applied voltage; the glow-like discharge can occupy the whole glass tube with an inner-diameter of 8.9 mm at a stable dis- charge mode; the optical emission spectrum shows that there are different kinds of chemically reactive species in the plasma jet region; the estimated length of the plasma jet (longer than 30 mml based on the modeling and experi- ments are consistent with each other qualitatively. The axial profile of the emission intensity of the plasma jet is re- lated with the de-excitation process of the metastables in the plasma jet region.关键词
