大气压脉冲介质阻挡放电长脉宽效应研究
|
摘要
大气压脉冲介质阻挡放电已得到广泛应用,它的机理和放电特征一直是人们关注的课题。文中对长脉宽脉冲电压作用下氩气放电等离子体进行了模拟研究,以给出这一放电所具有的特征的理论估计。模拟使用了一维流体模型,并对边界条件作了较严格的理论处理,这一处理使得在不同脉宽下计算的放电电流与实验符合得更好。应用建立的流体模型,分别对长脉宽和相应的短脉宽下的放电电流峰值、各粒子密度的空间分布、电场强度的轴向分布等作了计算和比较,对各态氩粒子的产生反应路径及其贡献进行了分析。文中研究表明:长脉宽下的计算结果与相应的短脉宽的结果呈现交换对称的特征;无论是长脉宽还是相应的短脉宽,放电模式均为典型的大气压辉光放电;改变脉宽对各态氩粒子反应路径的贡献影响较小。
Atmospheric-pressure pulsed dielectric barrier discharges have been widely applied,and its mechanisms and discharge characteristics are the topic of long(DBD)in argon gas at atmospheric pressure under long pulsewidths have been investigated numerically,so as to present the theoretical estimation for the characteristics of this discharge. A 1-D fluid model with an incorporation of the strict boundary conditions has been built for the present investigation. Using the built model,the discharge cur-rents calculated under different pulsewidths are in good agreement with the experiments. The discharge current den-sities and spatial distributions of the particle densities and electric field at long pulsewidths and at the correspond-ing short pulsewidths have been calculated and compared,the reaction pathways for the generation of argon parti-cles are presented,and the corresponding contributions have also been calculated. The present simulations show that in these two cases,i.e. long pulsewidths and the corresponding short pulsewidths,the calculated results are in exchange symmetry and the discharges are in the atmospheric-pressure glow discharge mode. In addition,the effects of pulsewidth on the reaction pathway contributions are very small.
