[en] The problem of radiative heat transfer through a gray, emitting, absorbing, and scattering medium with uniform optical properties is reduced to one without scattering through two techniques. One uses scaling laws, and the other uses a self-consistent effective gas temperature. The scaling laws are derived via the P₁ approximation to the radiative transfer equation and can be applied to multidimensional problems with nonisothermal media. The effective temperature method is presently restricted to isotropic scattering and isothermal media. Both methods are evaluated in the current study as a function of scattering albedo, wall emissivity, and optical thickness for two different geometries, and two sets of wall and gas temperatures. The effects of scattering anisotropy are also assessed for the P₁ method. The numerical results show that for these cases the scaling method is reasonably accurate for optically thick media with a scattering albedo less than 0.8, and the effective temperature technique is reasonably accurate for optically thin media for all albedos. 10 refs., 8 figs., 2 tabs
