Numerical simulation of rarefied dusty plasma in a normal glow discharge

A self-consistent model of a glow discharge, burning in a normal current density mode, with dust particles placed in it is presented. The model of a normal glow discharge is based on a diffusion-drift approximation. Within the framework of this model, the regions of a spatial charge are taken into account. The motion of dust particles in the glow discharge region is calculated using the method of molecular dynamics. The particle charge is estimated based on qualitative conceptions on the process of charging of solid particles. The proposed model is studied numerically, and the corresponding results are presented.
