Model of the nonequilibrium ionization process taking into account the level kinetics and radiation transport in the channel of plasma accelerator

New model for a numerical study of the ionizing gas flows in the channel of the quasi-steady plasma accelerator is presented. The model is based on the modified MHD equations for a medium consisting of atoms, electrons and ions, taking into account the electrical conductivity and thermal conductivity of a multicomponent medium, as well as the equations of level kinetics and the equation of radiation transport.
