In this experiment,the volume dielectric barrier discharge and the surface dielectric barrier discharge are realized by using different wire-wire electrode structures at atmospheric pressure.The single period discharge image,voltage current waveform and photocurrent waveform are collected under different airflow conditions,and the influence of airflow on discharge is studied and discussed.The results show that the flow affects the discharge pattern by changing the distribution of charged particles in the discharge space,which is more obvious in the volume dielectric barrier discharge.At the same time,the air flow can carry away the heat in the discharge space,so that the discharge intensity is weakened.
