V. Kuznetsov, Auteur ; M. A. Sheremet, Auteur Article en page(s) : pp. [081401-1/9] Note générale : Physique Langues : Anglais (eng) Mots-clés : Convection modes Conjugate heat transfer Laminar flow Heat source Index. décimale : 536 Chaleur. Thermodynamique Résumé : Laminar conjugate heat transfer in a rectangular area having finite thickness heat-conducting walls at local heating has been analyzed numerically. The heat source located on the left wall is kept at constant temperature during the whole process. Conjugate heat transfer is complicated by the forced flow. The governing unsteady, two-dimensional flow and energy equations for the gas cavity and unsteady heat conduction equation for solid walls, written in dimensionless form, have been solved using implicit finite-difference method. The solution has been obtained in terms of the stream function and the vorticity vector. The effects of the Grashof number Gr, the Reynolds number Re, and the dimensionless time on the flow structure and heat transfer characteristics have been investigated in detail. Results have been obtained for the following parameters: 103 DEWEY : 536 ISSN : 0022-1481 En ligne : http://asmedl.aip.org/vsearch/servlet/VerityServlet?KEY=JHTRAO&ONLINE=YES&smode= [...] [article] Numerical simulation of convective heat transfer modes in a rectangular area with a heat source and conducting walls [texte imprimé] / G.
