Validated Modeling of Atmospheric-Pressure Anodic Arc

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.
