Evaluation of energy transfer to arc discharge anode in inert gases

A.V. Ershov, O.G. Bykovsky

Zaporozhie National Technical University, Zaporozhie, Ukraine

Abstract
System of equations and boundary conditions are considered for calculation of near-anode zone of temperature- and ionization-nonequilibrium plasma of inert gases at the absence of molecular impurities. The effect of non-equilibrium in argon plasma and distribution of energy fluxes on anode between electrons, atoms and ions is shown
Keywords: anode, gradient, diffusion, concentration, ioni¬zation, ionization and thermal nоn-equilibrium, volume charge, voltage drop, Knudsen layer
