Abstract

The paper is one of a cycle of numerical investigations of two-dimensional flows of plasma in the channel of a plasma accelerator. The channel is formed by two coaxial electrodes. The current between them generates an azimuthal magnetic field, and the interaction of the current with the field leads to acceleration of the plasma. The flow is calculated on the basis of the two-dimensional axisymmetric non-stationary magnetohydrodynamic equations [1]. Attention is concentrated on the process of ionization of the gas in the channel, this being simulated by a discontinuous dependence of the conductivity on the temperature: Rem = σ0 for T < T* and σ1 + σ2· T3/2 for m ⩾ T*.
