Public ISBD [article]  in Journal of heat transfer > Vol 134 N° 9 (Septembre 2012) . - 05 p. Titre : View factors of samples tested in cone and cylinder calorimeters Type de document : texte imprimé Auteurs : Marcos J. A. Gemaque, Auteur ; Fernando S. Costa, Auteur Année de publication : 2012 Article en page(s) : 05 p. Note générale : heat transfer Langues : Anglais (eng) Mots-clés : cone  calorimeter;  view  factor  distribution;  total  view  factor Index. décimale : 536 Chaleur. Thermodynamique Résumé : Cone and cylinder calorimeters are devices used to determine flammability characteristics of solid materials under prescribed heat inputs. Temperature and heat input distribution on the exposed surface of a specimen in a calorimeter can be affected by variations of position or size of the specimen. This work analyzes the thermal radiation view factors of slabs and cylinders tested in cone and cylinder calorimeters, respectively. Blackbody radiation thermal interchange is assumed and reflections of neighbor objects are not considered. Uniformity of view factor distributions and total view factors are compared for slabs and cylinders tested in calorimeters, considering positioning and size variations.
