The interaction of radiation with conduction is investigated under steady-state conditions for a two-layer, absorbing, emitting, and isotropically scattering slab with a semitransparent interface. The outer boundaries are assumed to be black and are subjected to constant but different temperatures. An analytic approach is applied to solve the radiation part of the problem. A finite difference scheme is used for the solution of the conduction part. The reflectivities on both sides of the interface, and the relative magnitudes of the radiation and conduction properties of the layers, have significant effect on the temperature distribution in the medium, as well as on the proportion of the production and radiation fluxes in the medium. The effects of the conduction-to-radiation parameter, the single scattering albedo, the optical thickness, and the interface reflectivity on the temperature distribution and heat flux are examined. 10 references.
