The influence of thickness on the effective thermal conductivity in a thermal radiation absorbing and emitting media are considered. Our results, obtained by solving the radiative transfer equation (RTE - exact formulation), are compared with the Poltz-Jugel model developed for conductivity measurements in liquids and Andre-Degiovanni model developed for conductivity measurements in float glasses.
