Simulations of High Non-Uniform Electric Field in Dielectric Barrier Electrode System

An electric field in the dielectric barrier electrode system is necessary for ozone production because produced by discharge of O2 under a high-intensity field. The gas plasmas contain energetic particles, such as electrons, ions, atoms, and radicals. recombination O atom plasma will form O3. In this paper, dependence DC formation on geometry gap between electrodes materials were examined using computational modeling. Thus, set geometry, distance, material obtained uniform generation. COMSOL Multiphysics software was used Among geometries plate-plate, pin-plate mesh-plate, mesh-plate generated modeling, materials, including quartz, mica, alumina, water, compared. highest intensity occurred water surface. HIGHLIGHTS When distance two parallel less than 100 mm, constant, independent space A grounded when fine mesh high-voltage utilized With electrode, about times higher conventional plate electrodes, whereas uniformity 90 %. Therefore be initiated with lower high voltage GRAPHICAL ABSTRACT
