  We performed self-consistent modeling of the atmospheric-pressure plasmas
produced by arc discharges. Special numerical procedure for coupling of the
plasma current, emission current, ion current, sheath voltage drop, heat fluxes
at plasma-electrode interfaces was developed and implemented into the ANSYS CFX
code. Validation of the simulation results is performed through comparison of
simulation results with the previously available experimental data obtained by
a range of various plasma diagnostics.
