大气压氦气辉光放电中正柱区消散特性对时域非线性行为的影响
Influence of Positive Column Dissipation Characteristics on Temporal Nonlinear Phenomena in Atmospheric Helium Glow Discharges
摘要
Abstract
The atmospheric pressure glow discharge (APGD) generated by dielectric barrier structure has numerous nonlinear dynamic phenomena.In order to determine the detailed relationship between the dissipation characteristics of positive column and temporal nonlinear behaviors in APGD,we investigated the evolution trajectories of temporal nonlinear phenomena in APGDs via a one-dimensional fluid model of atmospheric helium dielectric barrier discharge (DBD).Furthermore,we elaborately analyzed the ratio of tp (the time interval between the generation and evanishment of positive column) and Tv (the period of applied voltage),as well as their relationship with the discharge modes.The results suggest that,if the value of tp/Tv is in the interval of (N,N+0.5),the period multiplication number of the discharge n satisfies the equation m=2N+l.When tp/Tv is in the interval of (N+0.5,N+1),there exists n1=N+1.Moreover,with the increase of driving frequency,the value tp/Tv also rises in certain ranges,thus the order by which the nonlinear phenomena appear is affected.This study determines the quantitative relationship between the dissipation rate of positive column and the dynamic state of APGDs,and proposes a preliminary explanation on the occurring sequence of these dynamic states.The results help to promote a better understanding on the mechanisms of nonlinear phenomena in APGDs.关键词
