Subject of the study: The distribution of the electric field in the air gap. Purpose of the work: To determine the influence of the dimensions and shape of water films and droplets in the interelectrode gap of a PBD system with two or more plane-parallel electrodes on the uniformity and intensity of the electric field distribution, which affects the efficiency of water purification from organic contaminants. Research methods: Mathematical modeling of the electric field using numerical methods. The study included modeling the electrostatic field in three-dimensional and two-dimensional setups based on the Laplace equation. The influence of droplet conductivity on the field strength in the air gap was analyzed. A formula was proposed to calculate the optimal distance between water droplets along the interelectrode gap for a given field strength. A two-dimensional discharge chamber model was developed to calculate the electric field with a constant average field strength in the air gap and a fixed droplet or stream surface area regardless of radius. The electric field strength and forces acting on droplet surfaces were analyzed depending on droplet radius and arrangement. An expression was derived to calculate the optimal droplet or stream volume for achieving a uniform field distribution and minimizing electric forces on droplets. The electrostatic field in a multi-electrode system was also analyzed. An equivalent circuit was developed to study currents and voltages. Comparative analysis of current, voltage, power, and discharge energy for various pulse durations was conducted. Product Description popup.authors Bereka Vladyslav О. popup.nrat_date 2024-12-18 Close
