Radiation Heat Transfer in Thermal Argon Plasma with Iron Vapors
Keywords:radiation transfer, P1-approximation, mean absorption coefficients
The objective of this paper consists of approximate calculations of thermal radiation heat transfer in ar-gon arc plasma with admixtures of iron vapors. As a mathematical tool, the P1-approximation has been used. To simplify the calculations, the frequency dependence of absorption coefficients has been handled by means of Planck and Rosseland averaging methods. Calculations has been performed for isothermal cylindrical plasma of various radii (0.01 to 10 cm) in temperature range 1 000 – 30 000 K.
