Numerical Studies on the Modulated Strategy of Atmospheric Pressure Dielectric Barrier Discharge Plasmas Driven by Dual-Frequency
摘要
Abstract
As a developing innovative technology,the modulation strategy with dual-frequency can effectively enhance plasma properties of atmospheric pressure dielectric barrier discharges (DBDs) and provide a possible approach to control and optimize the key plasma parameters,even realize the separate control of the electron density and gas temperature.In this paper,a self-consistent fluid model coupling the semi-kinetics method is used to study the plasma discharge characteristics and the impacts of different matching modes on the key plasma parameters.Thus,the basic strategy for the modulation method is acquired based on the nonlinear coupling gain between two frequencies.Besides,the separate tuning mechanism is analyzed by means of the spatial evolutions of electron density,ion density,electric field and impact ionization of electrons.The work is important for deep understanding of the dual-frequency modulated DBD plasmas as well as the promotion of the associated applications.关键词
