Empirical Stationary Condition of Two-Dimensional Flows of Ionizing Hydrogen in the Plasma Accelerator Channel

Stationary and unstable pulsating flows of ionizing hydrogen in the channel of a quasi-stationary plasma accelerator are considered. Numerical studies of two-dimensional axisymmetric flows are carried out based on the modified magnetogasdynamic (MGD) 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 two-dimensional flows of an ionizing gas.
