Comparison on Discharge Characteristics of Gas-liquid Two-phase Dielectric Barrier Discharge with Different Electrode Structures
摘要
Abstract
The discharge characteristics of dielectric barrier discharge(DBD) in gas-liquid mixture with the edgeplate,tube-plate,and mesh wire-plate electrode structures at atmospheric pressure in air were studied and compared by measuring voltage and current waveforms,taking lighting emission images,and using spectrum analysis.The changing trends of electrical parameters with the applied voltage were studied.Moreover,the discharge characteristics of DBD in gas-liquid mixture with different electrode structures were analyzed by combining gas discharge theory.The results show that the voltage and current waveforms,Lissajous figures,and optical emission spectrum of three electrode structure DBDs in gas-liquid mixture show different characteristics.At the same experimental conditions,the mesh wire-plate electrode structure DBD in gas-liquid mixture has the strongest discharge and the largest dissipated discharge power,and the discharge current can reach 140 mA.The arrangement of the electrode leads to difference non-uniform coefficient on electric field distribution, which is the main reason for the difference on discharge characteristics.With the increase in voltage amplitude,the discharge become strong,and the discharge power,molecular vibrational temperature and electron excited density all increase.关键词
