Radiation Energy Transfer in Arc Plasma
Keywords:
electric arc, absorption coefficient, radiation transfer, Planck and Rosseland meansAbstract
The article deals with the approximation method which is used to solve the equation of transfer radiation energy in cylindrical thermal arc plasma. The frequency-dependent variables of the equation of radiation transfer and net emission values are calculated by means of the multigroup method and average magnitudes which are determined by two different ways such as Planck and Rosseland means methods.References
