Résumé

Stationary and unstable pulsating flows of ionizing hydrogen in the channel of quasistationary plasma accelerator are considered. Numerical studies of two-dimensional axisymmetric flows were carried out on the basis of the modified MHD equations in the approximation of local thermodynamic equilibrium, taking into account electrical conductivity, thermal conductivity, and radiation transport. The generalization of the calculation results led to the formulation of the empirical condition for the stationarity of twodimensional flows of ionizing gas.

Détail

Keywords: ionizing gas flows, equations of magnetic gas dynamics, flow stationarity condition, plasma accelerator.
