Coupled radiative and conductive heat transfer in a non-grey absorbing and emitting semitransparent media under collimated radiation
Résumé
This paper deals with heat transfer in non-grey semitransparent two-dimensional sample. Considering an homogeneous purely absorbing medium, we calculated the temperature ÿeld and heat uxes of a material irradiated under a speciÿc direction. Coupled radiative and conductive heat transfer were considered. The radiative heat transfer equation (RTE) was solved using a S 8 quadrature and a discrete ordinate method. Reeection and absorption coeecients of the medium were calculated with the silica optical properties. The conduction inside the medium was linked to the RTE through the energy conservation. Validation of the model and two original cases are also presented. ?
