TWO-FLUID MAGNETOHYDRODYNAMIC MODEL OF PLASMA FLOWS IN A QUASI-STEADY-STATE ACCELERATOR WITH A LONGITUDINAL MAGNETIC FIELD

摘要

This paper reports the results of numerical studies of axisymmetric flows in a coaxial plasma accelerator in the presence of a longitudinal magnetic field. The calculations were performed using a two-dimensional two-fluid magnetohydrodynamic model taking into account the Hall effect and the conductivity tensor of the medium. The numerical experiments confirmed the main features of the plasmadynamic processes found previously using analytical and one-fluid models and made it possible to study plasma flows near the electrodes.
