Heat and mass transfer enhancement for falling film absorption process by SiO2 binary nanofluids / Hyundae Kim 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. 645–651 Titre : Heat and mass transfer enhancement for falling film absorption process by SiO2 binary nanofluids Titre original : Amélioration du transfert de chaleur et de masse lors du processus d'absorption sur un film tombant faisant appel aux nanofluides binaires au SiO2 Type de document : texte imprimé Auteurs : Hyundae Kim, Auteur ; Jinhee Jeong, Auteur ; Yong Tae Kang, Auteur Année de publication : 2012 Article en page(s) : pp. 645–651 Note générale : Génie mécanique Langues : Anglais (eng) Mots-clés : Water–lithium  bromide  Distribution  Stability  Absorption  system  Enhancement Résumé : The objectives of this study are to visualize the dispersion of nano-particles in binary nanofluids, to find the effect of key parameters such as SiO2 nano-particles concentration on the distribution stability in the H2O/LiBr nanofluids, and to measure the vapor absorption rate and heat transfer rate for falling film flow of binary nanofluids. The binary nanofluids are H2O/LiBr with SiO2 nano-particle. The key parameters are the base fluid concentration of LiBr, the concentration of SiO2 nano-particles in vol%, and kinds of additives. It is found that the concentration of SiO2 nano-particles should be less than 0.01 regardless of the existence of the distribution stabilizer. It is also found that the maximum improvements of heat transfer rate and mass transfer rate reach 46.8% and 18%, respectively, when the concentration of SiO2 nano-particle is 0.005 vol%.
