Abstract
The characteristics of water spray have been measured in the presence of dielectric barrier discharge in the region where the film of liquid flowing out of the nozzle hole disintegrates into droplets. The discharge has been initiated in the region between the water film and the high-voltage electrode surrounded by a dielectric material. The measurements were performed using the direct shadow method based on obtaining multiple shadow instantaneous microphotographs of droplets. Current and voltage oscillograms in the barrier discharge initiation circuit have been recorded. The average parameters, such as the average diameter and Sauter mean diameter, of droplets have been compared in two cases: without discharge initiation and when it has been created in the region where the spray is formed, at a voltage frequency of 5 kHz and its amplitude of 10 kV. It is shown that in the case of discharge initiation, the average parameters of droplets significantly decrease and their number increases.
期刊介绍：
Plasma Physics Reports is a peer reviewed journal devoted to plasma physics. The journal covers the following topics: high-temperature plasma physics related to the problem of controlled nuclear fusion based on magnetic and inertial confinement; physics of cosmic plasma, including magnetosphere plasma, sun and stellar plasma, etc.; gas discharge plasma and plasma generated by laser and particle beams. The journal also publishes papers on such related topics as plasma electronics, generation of radiation in plasma, and plasma diagnostics. As well as other original communications, the journal publishes topical reviews and conference proceedings.
