Reduced models for radiative heat transfer analysis through anisotropic fibrous medium / Hervé Thierry Kamdem-Tagne in Journal of heat transfer, Vol. 132 N° 7 (Juillet 2010) 

Public ISBD [article]  in Journal of heat transfer > Vol. 132 N° 7 (Juillet 2010) . - pp. [072703-1/8] Titre : Reduced models for radiative heat transfer analysis through anisotropic fibrous medium Type de document : texte imprimé Auteurs : Hervé Thierry Kamdem-Tagne, Auteur ; Dominique Doermann Baillis, Auteur Article en page(s) : pp. [072703-1/8] Note générale : Physique Langues : Anglais (eng) Mots-clés : Anisotropic  medium  Isotropic  medium  Fibrous  Scattering  phase  function  Henyey-Greenstein  Conduction  Radiation Index. décimale : 536 Chaleur. Thermodynamique Résumé : Reduced models for radiative heat transfer analysis through anisotropic medium are presented and evaluated. The models include two equivalent heat transfer models through isotropic medium using isotropic or Henyey–Greenstein scattering phase functions with arithmetic or weighted means radiative properties calculated over all incident direction and an anisotropic model with directional radiative properties coupled to an isotropic scattering phase function or directional anisotropically scattering phase function. The pertinence of the models is investigated by solving coupled conduction/radiation heat transfer through a slab of anisotropic fibrous medium with fiber randomly oriented in the plan parallel to the boundaries. Good agreements on heat fluxes and thermal conductivity are obtained for reduced anisotropic models and for reduced equivalent isotropic models with weighted mean radiative properties.
