An investigation of the thermal conductivity of semitransparent materials in thin layers. I  Stationary heat transfer in a flat layer  Estimates of effective thermal conductivity
Abstract
It is noted that today analytic methods are preferred for excluding the radiation component in experimental investigations of the thermal conductivity of semitransparent substances. These methods, however, suffer from limitations on the amount of data available on the optical properties of the substances. The paper therefore seeks to obtain approximate relationships between the coefficient of molecular thermal conductivity and the effective thermal conductivity as measured in an optically thin layer. These relationships permit a simple calculation of the molecular thermal conductivity on the basis of a known effective conductivity and make it possible to estimate the parameters of experiments in which the molecular conductivity differs very little from the effective conductivity.
