Nongray Radiative Transfer in a Planar Medium Exposed to a Collimated Flux
The problem of energy transfer through a plane layer of an absorbing and emitting medium exposed on one side to a monochromatic collimated radiation flux is analyzed to determine the effect of line or band shape on radiative transfer. The analysis is restricted to a medium in local thermodynamic equilibrium and an absorption coefficient Kv of the Milne-Eddington type, i.e., Kv(T) = α(v)β(T). For the case when Kv consists of an array of equal intensity, nonoverlapping bands or lines, the solution for the source function and the radiative flux are expressed in terms of universal functions. Numerical solutions for the Chandrasekhar X and Y-functions are presented in graphical and tabular form for the rectangular, triangular, exponential, Lorentz and Doppler profiles. © 1970.
