Abstract:

In this paper, a new method for solving Maxwell's equations associated with electrostatic separators is presented. The boundary value problem is transformed into an optimization problem by using the finite element method. Numerical simulations were carried out using Matlab software that performs equation-based multiphysics modeling for different physical processes by applying the finite element method and modified method of characteristics to a system of partial differential equations. The finite-element method is used to solve Poisson's equation, and a modified method of characteristics is used to satisfy the current continuity condition. The two methods are repeated to obtain a consistent solution to the described equations. The simulation model has been developed to determine the influence of the electrical conductor, semiconductor, and dielectric particles on the important parameters of the corona mechanism, namely the distribution of electric potential, electric field, current density, space charge density, and collection efficiency.
