Subject of study: The distribution of the electric field in the air gap with water droplets in the discharge chamber for pulsed barrier discharge. The aim of the research is to develop two-dimensional and three-dimensional mathematical models of the electromagnetic field in the system of flat-parallel electrodes with inclusions in the interelectrode gap in the form of water droplets with specified electrical conductivity. This is done to investigate the influence of water conductivity on the distribution of the electric field in the interelectrode gap and the parameters of the barrier discharge setup using the finite element method, determining the influence of edge effects on the results of modeling in two-dimensional and three-dimensional formulations. Research methods include two-dimensional and three-dimensional mathematical modeling of the electric field using numerical methods. Sketches of the electrode device for modeling the electric field were developed, and equations for the electromagnetic field and boundary conditions for static modeling were determined. The impact of the electrical conductivity of water droplets and the distance between droplets on the distribution and intensity of electric field strength was investigated. A model for harmonic electric fields was developed, and the impact of water conductivity on the distribution of current density was analyzed. Investigations were carried out on edge effects which not considered in two-dimensional models, and the capacitance of the DC and the density of ohmic losses were established. An equivalent electrical circuit of the PBD DC was proposed to study transient processes of current and voltage in the DC with a specified power source. This study makes a significant contribution to understanding the influence of water conductivity and the distance between droplets. Product Description popup.authors Bereka Vladislav O.
