Abstract

This article examines the application of Yu. M. Davydov's coarse particle method (CPM) to numerical modeling of corona discharge dynamics in a cylindrical electrostatic precipitator. The author utilizes a unipolar model, including continuity equations for electric charge and Poisson's equation, implemented in MATLAB using the Thomas algorithm and the Runge-Kutta method. The calculated distributions of charge density, electric field strength, and current demonstrate high accuracy and good convergence with well-known analytical solutions by K. Lübbert and J. P. Raiser.
