高氧浓度下大气压Ar/O2脉冲介质阻挡放电频率特性数值研究
A Numerical Study on the Frequency Effects of the Electrical Characteristics of the Pulsed Dielectric Barrier Discharge in Ar/O2 with High Oxygen Concentration at Atmospheric Pressure
摘要
Abstract
By means of a 1-D fluid model, the effects of frequency on the atmospheric-pressure Ar/O2 pulsed dielectric barrier discharge (DBD) under high oxygen concentrations (1%~5.0%) were investigated. Under the considered frequency range below 100kHz and oxygen concentrations, the frequency dependences of the discharge current densities were calculated and analyzed. The results show that there are two bipolar discharges, one occurs at the rising edge ofVa and the other at the falling edge ofVa. Under different oxygen concentrations, the peak values of the two bipolar discharges first reduce and then increase with the increase of frequency, that is, there is a minimum value, where the corresponding frequency of each discharge can be defined as the characteristic frequency. The oxygen concentration dependences of the two characteristic frequencies corresponding to the two bipolar discharges, respectively, are obtained. In addition, when the oxygen concentration is 3.0%, the dominated reaction pathways for the production and consumption of four reactive species (O, O(1D), O2(1Δg) and O3) and their contributions at different frequencies are also given.关键词
