Abstract

This inquiry elucidates an analysis of a coaxial direct current corona discharge occurring under dry atmospheric conditions at ambient atmospheric pressure. The geometric parameters and operational conditions exhibit similarities to those generally encountered in electrostatic precipitators that utilize a wire-to-plate arrangement. The inner electrode is categorized by a radius of 100 µm, while the inter-electrode distance is recognized at 10 cm. The simulations performed are relevant to steady-state conditions, during which the discharge is sustained through the application of a voltage of 10 kV to the inner electrode, with the outer electrode being grounded. A primary focus of this investigation is the generation and transportation of charged particles, along with the ramifications of such phenomena on the current-voltage characteristics of the discharge.
