Abstract

The joint impact of an electrical discharge and a gas–droplet flow of a conducting liquid created by a centrifugal nozzle is studied. In the experiment, the electrical parameters of the discharge are recorded, and the local characteristics of the spray, namely, the droplet diameter distributions of the number of droplets and the components of their velocity vector are measured. The measurements are carried out using double shadow microphotography. The effect of a spray of a conducting liquid on the time-averaged electrical parameters of the discharge, as well as changes in the properties of the spray under the influence of high voltage and current, are studied. Additionally, the spray characteristics are measured when a high voltage of pre-breakdown value is applied. High-speed photography of a discharge in the presence of droplets of conducting liquid is carried out.

高压和放电等离子体下导电液体喷雾的形成

摘要

研究了离心喷嘴产生的导电液体的放电和气滴流的联合影响。在实验中，记录放电的电参数，并测量喷雾的局部特征，即液滴数量的液滴直径分布及其速度矢量分量。使用双影显微摄影进行测量。研究了导电液体喷雾对放电的时间平均电参数的影响，以及高电压和电流影响下喷雾特性的变化。此外，当施加预击穿值的高电压时测量喷雾特性。对存在导电液体液滴的放电进行高速摄影。
