Abstract
Methodical aspects for development of quasi-diffusive methods are presented for calculation of radiant heat transfer in absorbent, emissive and isotropic scattering gray medium in application to generalized statement of the problem. The heat transfer problem can be reduced to solution of approximate differential equations relative to the flux density of volumetric incident (or semispherical resulting) radiation. In turn, these equations can be reduced to differential equations for determination of the flux densities of volumetric and surface incident radiation with given generalized characteristics of radiation in volume and on boundaries
