Identification of macroscopic thermophysical properties during transient heat transfer processes : two-equation model and application to a stratified medium / C. Gobbé

Public ISBD Accompagne Advanced concepts and techniques in thermal modelling / J. Henriette Titre : Identification of macroscopic thermophysical properties during transient heat transfer processes : two-equation model and application to a stratified medium Type de document : texte imprimé Auteurs : C. Gobbé, Auteur ; J.L. Battaglia, Auteur ; M. Quintard, Auteur Importance : p 75-82 Langues : Anglais (eng) Catégories : MATHEMATIQUE-PHYSIQUE-CHIMIE Résumé : An inverse procedure is proposed to identify the macroscopic thermophysical properties of a two-phase heterogeneous during transient heat conduction processes. Macroscopic modelling is established using a volume averaging technique . In case of local thermal non-equilibrium, this leads to a two-equation model in which macroscopic properties are defined by six effective independent parameters. An identification procedure based on the Levenberg-Marquardt algorithm is proposed to identify the macroscopic properties in the case of stratified media.
