The effect of the plasma composition on characteristics of the d.c. arc - V The influence of iodine vapour on the radial temperature distribution of the arc burning in the atmosphere of nitrogen and argon

Abstract

Considering the solutions of the Elenbaas-Heller energy balance equation it is possible to indicate how the chemical reactions among the components of added substances influence the radial temperature distribution in the arc. In the case of addition of iodine vapour to the atmosphere of nitrogen, and argon respectively, a core of higher temperature with a larger gradient of the radial temperature distribution in the arc centre is formed. These conclusions are confirmed by experimental determinations of the radial temperature distribution.
