COMPARISON OF COLLISIONAL-RADIATIVE MODEL AND AVERAGE ION MODEL OF PLASMA KINETICS IN THE NON-LOCAL CASE

摘要

Two approaches to the development of a simplified model of non-equilibrium plasma kinetics have been discussed: chemical and solid-state ones. Within Bohr's ion model and Bohr's collisional-radiative model (BCRM) kinetics, the validity conditions of these two approaches are analysed based on ionic and configuration presentations of the initial approximation. The derivation of Bohr's average ion model (AIM) from BCRM and an analysis of the approximation accuracy in local thermodynamic equilibrium and coronal limits are given. The hydrogen-like Slater's AIM has been described.
