摘要/Abstract

摘要：

用XOOPIC软件对同轴圆筒状反应装置DBD放电特性进行了二维模拟研究。在频率为20kHz、正弦电压幅值为5kV的大气压氩气放电中，再现了微放电通道形成和发展过程，其微放电的寿命约为4ns。获得了电子、离子、介质表面电荷密度和电场强度随空间和时间的分布，发现在高压线圈的位置附近电子、离子和介质表面电荷密度存在极值。与典型平板介质阻挡放电相比，微放电中的电子密度、场强增加2~3个数量级。

Abstract:

Two-dimensional simulation research on coaxial cylinder reactor dielectric barrier discharge at atmospheric pressure have been carried out using XOOPIC software. The process of micro-discharge form and evolution reappeared and the life-span of micro-discharge was about 4ns in the atmospherical argon discharge with the 20kHz and 5kV power supply. The distribution of electronics density, ion density, barrier surface charge density and electric field with the space and time were obtained. Extreme values of electron density, ion density and barrier surface charge density exist around anode on the dielectric surface. Comparing with typical flat panel DBD, electronics density and field intensity in the filamentary characteristic increase 2~3 order of magnitude.
