Boundary-condition-independent reduced-order modeling of heat transfer in complex objects by POD-Galerkin methodology / Arun P. Raghupathy in Journal of heat transfer, Vol. 132 N° 6 (Juin 2010) 

Public ISBD [article]  in Journal of heat transfer > Vol. 132 N° 6 (Juin 2010) . - pp. [064502-1/4] Titre : Boundary-condition-independent reduced-order modeling of heat transfer in complex objects by POD-Galerkin methodology : 1D case study Type de document : texte imprimé Auteurs : Arun P. Raghupathy, Auteur ; Urmila Ghia, Auteur ; Karman Ghia, Auteur Article en page(s) : pp. [064502-1/4] Note générale : Physique Langues : Anglais (eng) Mots-clés : Computational  fluid  dynamics  Finite  volume  methods  Galerkin  method  Heat  transfer  Matrix  decomposition  Thermal  management  (packaging) Index. décimale : 536 Chaleur. Thermodynamique Résumé : This technical note presents an introduction to boundary-condition-independent reduced-order modeling of complex electronic components using the proper orthogonal decomposition (POD)-Galerkin approach. The current work focuses on how the POD methodology can be used along with the finite volume method to generate reduced-order models that are independent of their boundary conditions. The proposed methodology is demonstrated for the transient 1D heat equation, and preliminary results are presented.
