  abstract = {A novel non-equilibrium model has been developed to describe the interplay
	of heat and mass transfer and electric and magnetic fields in a DC
	electric arc. A complete diffusion treatment of particle fluxes,
	a generalized form of Ohm’s law, and numerical matching of the arc
	plasma with the space-charge sheaths adjacent to the electrodes are
	applied to analyze in detail the plasma parameters and the phenomena
	occurring in the plasma column and the near-electrode regions of
	a DC arc generated in atmospheric pressure argon for current levels
	from 20 A up to 200 A. Results comprising electric field and potential,
	current density, heating of the electrodes, and effects of thermal
	and chemical non-equilibrium are presented and discussed. The current–voltage
	characteristic obtained is in fair agreement with known experimental
	data. It indicates a minimum for arc current of about 80 A. For all
	current levels, a field reversal in front of the anode accompanied
	by a voltage drop of (0.7–2.6) V is observed. Another field reversal
	is observed near the cathode for arc currents below 80 A.},
