Abstract:
The temperature as well as specific and integrated powers of energy mechanisms for sustaining a steady equilibrium arc discharge in a cylindrical channel in argon and carbon dioxide under atmospheric pressure are determined by solving the Elenbaas–Heller equation for various values of current $I$ and radius $R$. The results of computations are represented in the form of state diagrams intended for estimating the main energy parameters of electric arcs for preset values of $I$ and $R$. For carbon dioxide, the effect of screening of the heat conduction mechanism at the discharge boundary, which is due to a peculiar temperature dependence of radiation properties, is detected.
