Research of the non-stationary pulsing modes of the ionizing gas flow is carried out in the channel of the plasma accelerator with the azimuthal magnetic field. The MHD-equations added by the ionization and recombination kinetics equation within the framework of the modified diffusion approximation taking into account the photo ionization and photo recombination are put in a basis of model. The basic mechanisms of the electro conductivity and heat transfers in the three-component medium consisting of atoms, ions and electrons are presented.
