高斯电压驱动大气压氩气介质阻挡放电的特性研究
|
摘要
本文采用一维自洽流体模型理论研究了高斯电压驱动下大气压氩气介质阻挡放电的放电特性.在特定的频率、振幅和气隙间隔条件下,得到了气隙电压和放电电流随时间的变化关系,以及放电气隙中电子、离子和电场的空间分布特征.模拟结果表明,高斯电压驱动下的大气压氩气介质阻挡放电是一个多电流脉冲放电,存在两种放电模式:汤森模式和辉光模式.在每半个放电周期内,放电经历一个在汤森模式与辉光模式之间的转变过程,气隙空间电荷和介质表面电荷是造成放电模式转变的主要因素.此外,下降沿残余电流峰的出现,是源于上升沿放电残留了大量的空间电荷.上述仿真结果为等离子体在材料表面处理、污染治理,以及生物医学等领域中电压激励源的设计提供了新的思路.
A one-dimensional self-consistent fluid model is employed to investigate the atmospheric-pressure argon dielectric-barrier discharge(DBD) excited by periodic Gaussian voltage.With the driving frequency,voltage amplitude,and gas gap set at certain values,the temporal evolutions of discharge current density and gas voltage are obtained,together with the spatial distributions of electron and ion densities and electric field.Simulation results indicate that there are two discharge modes:Townsend and glow modes in the multi-current pulse discharge.A mutual transition between the Townsend mode and glow one occurs during each half cycle of the applied Gaussian voltage.The space charges in the gas gap and the surface charges on the dielectrics play a key role in the transition between the two discharge modes.Additionally,a residual current peak is observed during the falling phase of each half cycle.This is resulted from the fact that amounts of space charges are trapped in the gas gap during the rising phase of the applied Gaussian voltage.These findings contribute much to the design of plasma excitation source in applications,such as materials processing,pollution control,and biomedical sterilization.
