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.
