The spatial electron fluxes, which arise in inhomogeneous plasmas in external fields
play important role in low-temperature plasma. They result in a redistribution of particles and
energy in the plasma volume, loss and generation of plasma. Moreover, these differential
fluxes can be directed both inward and outward producing nontrivial behavior of spatial
plasma characteristics in non-local plasmas [1].
In this paper modeling of discharge column gas plasma is proceeded to reveal
phenomena which result from their complicated structure at moderate and high pressures
when EDF is formed by energy exchange in elastic collisions (Dryuvestein –Davydov EDF).
Computational simulation for argon gas consisted of Ar atoms, metastable atoms Ar*,
radiating Ar**, positive ions Ar+, and electrons have been performed. The model involves
direct ionization, electronic excitation from ground-state atoms, step-wise ionization from
metastables, Penning ionization, and de-excitation. To provide simulations COMSOL
