Public ISBD [article]  in International journal of refrigeration > Vol. 36 N° 8 (Décembre 2013) . - pp. 2233–2241 Titre : Particle shape effect on the viscosity and thermal conductivity of ZnO nanofluids Titre original : Effet de forme de particules sur la viscosité et la conductivité thermique de nanofrigorigènes ZnO Type de document : texte imprimé Auteurs : Jisun Jeong, Auteur ; Chengguo, Li, Auteur ; Younghwan, Kwon, Auteur Année de publication : 2014 Article en page(s) : pp. 2233–2241 Note générale : Refrigeration Langues : Anglais (eng) Mots-clés : ZnO  nanofluids;  heat  transfer;  thermal  conductivity;  viscosity;  shape  effect Résumé : The viscosity and thermal conductivity of ZnO nanofluids with nanoparticle shapes of nearly rectangular and of sphere, were experimentally investigated under various volume concentrations of the nanoparticles, ranging from 0.05 to 5.0 vol.%. The viscosity of the nanofluids increased with increases in the volume concentration by up to 69%. In addition, the enhancement of the viscosity of the nearly rectangular shape nanoparticles was found to be greater by 7.7%, than that of the spherical nanoparticles. The thermal conductivity of the ZnO nanofluids increased by up to 12% and 18% at 5.0 vol.% for the spherical and the nearly rectangular shape nanoparticles, respectively, compared to that of the base fluid (water). The shape of the particles is found to have a significant effect on the viscosity and thermal conductivity enhancements.
