Abstract
Abstract The paper devoted to the research of the microdischarge dynamics in the dielectric barrier discharge. The discharge between rail electrodes in airflow along the electrodes at atmospheric pressure was studied. The aim of this work is to clarify the role of volume plasma and surface charges in the memory effect of microdischarges. Based on the analysis of microdischarge images obtained using high-speed camera, it is established that the transport of microdischarge plasma by a gas flow determines the microdischarge localization in each subsequent half-cycle of the applied voltage. An important part is played by the turbulence and the presence of vortices in the airflow. They determine both the speed of plasma channel transfer and the probability of the microdischarge appearence in a specific half-cycle. The results of the work show the possibility of the gas-dynamic control for parameters of a barrier discharge.
