Abstract
In this paper the dynamic contraction of the current channel inside a quasineutral positive column of a glow discharge in a rectangular duct with the convection cooling is studying. A set of time-dependent two-dimensional equations for the case of molecular nitrogen was formulated, and then solved numerically. It is shown that when the threshold condition for the ionization-thermal instability is fulfilled the initial perturbation formed by a high density plasma filament near one electrode then propagates to the opposite electrode. The developed steady-state contracted discharge is uniform along the direction of the current.
