Combined conduction and radiation in an absorbing, emitting, and scattering planar medium bounded by diffuse surfaces is analyzed for the case of a prescribed heat flux on one boundary and a prescribed temperature on the other. The problem is solved using the Galerkin finite element method which yields the flux and the temperature directly as the unknowns in the formulation. Effects of the conduction-radiation parameter, surface emissivity albedo, and incident flux are discussed. Results are found to be in excellent agreement with other solutions reported in the literature.
