Characteristics of a Nanosecond Discharge with a Liquid Nonmetallic Electrode in the Air

Abstract

A module for a high-current nanosecond discharge above the liquid surface (distilled water and ethyl alcohol solution) is developed, and the results are presented in this article. The electrical and optical characteristics of the discharge are examined. The conditions for the ignition of a discharge above the fluids based on ethyl alcohol and distilled water and the discharge between a metal (blade) electrode and a liquid electrode are defined. These discharges are of interest for use in water purification systems (to purify the surface of water from organic films) and for the synthesis of nanoparticles (carbon).
