Numerical investigation of coupled heat and mass transfer inside the adsorbent bed of an adsorption cooling unit / İsmail Solmuş in International journal of refrigeration, Vol. 35 N° 3 (Mai 2012) 

Public ISBD [article]  in International journal of refrigeration > Vol. 35 N° 3 (Mai 2012) . - pp. 652–662 Titre : Numerical investigation of coupled heat and mass transfer inside the adsorbent bed of an adsorption cooling unit Titre original : Etude numérique sur le transfert de chaleur et de masse à l’intérieur du lit absorbant d’un système de refroidissement à adsorption Type de document : texte imprimé Auteurs : İsmail Solmuş, Auteur ; D. Andrew S. Rees, Auteur ; Cemil Yamalı, Auteur Année de publication : 2012 Article en page(s) : pp. 652–662 Note générale : Génie mécanique Langues : Anglais (eng) Mots-clés : Adsorption  Adsorbent  Cooling  Silica  gel Résumé : In this study, the influence of several design parameters on the transient distributions of temperature, pressure and amount adsorbed in the radial direction of a cylindrical adsorbent bed of an adsorption cooling unit using silica gel/water have been investigated numerically. For this purpose, a transient one-dimensional local thermal non-equilibrium model that accounts for both internal and external mass transfer resistances has been developed using the local volume averaging method. For the conditions investigated, the validity of the local thermal equilibrium and spatially isobaric bed assumptions have been confirmed. To improve the performance of the bed considered, efforts should be focused on reducing heat transfer resistances and intra-particle (interior) mass transfer resistances but not inter-particle (exterior) mass transfer resistances.
