Abstract :
A multidimensional fluid model of the DC elevated pressure glow discharge has been used to study the growth of the instability near an anode inside a parallel plane surface geometry. This model is based on a fluid description of electron and ion transport coupled with Poisson´s equation. The numerical results of studies of the anode glow stratification, resulting in the formation of separate glowing regions extended along the gas flow, are presented. The electron diffusion, full current, and volume electron-ion recombination have a profound effect on the collective interaction of current structures
