Abstract
This paper deals with the evaluation of radiation properties of air arc plasma with various admixtures of Cu, Ag, and Fe, respectively. Under assumption of isothermal plasma cylinder, the net emission coefficients were calculated for various arc radii as a function of the plasma temperature up to 30 000 K. For plasma with prescribed temperature profile, the equation of radiation transfer was solved in the P1 approximation, and the radiation flux and its divergence were calculated.
