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.

气流阻挡放电中微放电的记忆效应

摘要

本文致力于介质阻挡放电中微放电动力学的研究。研究了大气压下沿电极流动的轨道电极之间的放电情况。这项工作的目的是阐明体积等离子体和表面电荷在微放电记忆效应中的作用。基于使用高速相机获得的微放电图像的分析，可以确定通过气流的微放电等离子体的传输确定了施加电压的每个后续半周期中的微放电定位。气流中的湍流和涡流的存在是重要的部分。它们确定了特定通道半周期中的等离子体通道传输速度和微放电出现的可能性。
