Original Abstract

The objective of this paper consists of approximate calculations of radiative heat transfer in SF6 arc plasmas at the plasma temperatures in the range of 1000 – 35 000 K and pressures from 0.5 to 5 MPa. As a mathematical tool for the radiation field prediction, the P1-approximation was used. To simplify the calculations, the frequency dependence of absorption coefficients has been handled by means of Planck and Rosseland averaging methods. Calculations have been performed for cylindrical plasma of various radii (0.01 – 10) cm with given temperature profile. Contribution to the net emission of different spectral regions is discussed.
