摘要：
The study of the axisymmetric ionizing gas flows in a channel of the quasi-steady plasma accelerator is presented. Model is based on the MHD and radiation transport equations. The MHD model for a three-component medium consisting of atoms, ions and electrons takes into account the basic mechanisms of the electrical conductivity and heat transport. The model of the radiation transport includes the basic mechanisms of emission and absorption for the different parts of the spectrum. Results of the numerical studies of ionization process and radiation transport are obtained in the approximation of the local thermodynamic equilibrium. (C) 2017 Elsevier B.V. All rights reserved.
