The use of reduced models to solve inverse heat transfer problems / E. Videcoq

Public ISBD Accompagne Advanced concepts and techniques in thermal modelling / J. Henriette Titre : The use of reduced models to solve inverse heat transfer problems Type de document : texte imprimé Auteurs : E. Videcoq, Auteur ; D. Petit, Auteur ; H. Sadat, Auteur Importance : p 125-132 Langues : Anglais (eng) Catégories : MATHEMATIQUE-PHYSIQUE-CHIMIE Mots-clés : TRANSFERT DE CHALEUR  MODELISATION REDUITE Résumé : In the case of a large system, the numerical modelling of the transient diffusion equation leads to a vector differnetial equation of large size. In order to treat Inverse Heat Conduction Problems (IHCP), such as the identification of thermal stimulations from measured temperatures, the use of this type of model is very difficult . Here, we propose an original way for IHCP, by using a Reduced Model (RM) which retains in a simple and stable way, the relations between the thermal inputs and outputs that are observed. This RM, built with dominant eigenmodes, acts as a filter in high frequencies and leads to a precise and well-conditioned algorithm when future time steps are added.
