Problems of the radiation theory of heat and mass transfer in solid and liquid media

A mechanism and foundations of the radiation theory of heat and mass transfer that are based on the transfer of energy by photons emitted and absorbed by particles of the substance are presented. Equations of heat and mass transfer that transform, in the limit, to known phenomenological equations, energy distribution functions of atoms and their degrees of freedom in diffusion processes, and expressions for the specific heat and the diffusion coefficient that yield, as particular cases, the known Debye, Arrhenius, and Einstein formulas have been found.z Translated from Inzhenerno-Fizicheskii Zhurnal, Vol. 73, No. 4, pp. 851–859, July–August, 2000.
