The steady energy transfer equation by simultaneous conduction and radiation in an absorbing, emitting and nonscattering gray planar medium is studied theoretically. For extremely high-temperature applications, where radiative transfer plays an important role, ceramic-matrix composites, considered as semitransparent materials, are being explored for potential use in turbine and compressors components, spacecraft structures, engine control systems and nuclear reactors. Exact solution of the

A technique combining an accurate physical formulation, the two-flux model, coupled to a fast numerical procedure for the calculation of the temperature and heat fluxes is described.
