CO2 bubble absorption enhancement in methanol-based nanofluids / Jae Won Lee in International journal of refrigeration, Vol. 34 N° 8 (Décembre 2011) 

Public ISBD [article]  in International journal of refrigeration > Vol. 34 N° 8 (Décembre 2011) . - pp. 1727–1733 Titre : CO2 bubble absorption enhancement in methanol-based nanofluids Titre original : Amélioration de l'absorption des bulles de CO2 dans les nanofluides à base de méthanol Type de document : texte imprimé Auteurs : Jae Won Lee, Auteur ; Jung-Yeul Jung, Auteur ; Soon-Geul Lee, Auteur Année de publication : 2012 Article en page(s) : pp. 1727–1733 Note générale : Génie mécanique Langues : Anglais (eng) Mots-clés : Absorption  Enhancement  Bubble  Carbon  dioxide  Methanol  Particle Résumé : In this study, the nanoparticles (i.e. SiO2 and Al2O3 nanoparticles) and methanol are combined into SiO2/methanol and Al2O3/methanol nanofluids to enhance the CO2 absorption rate of the base fluid (methanol). The absorption experiments are performed in the bubble type absorber system equipped with mass flow controller (MFC), mass flow meter (MFM) and silica gel (which can remove the methanol vapor existing in the outlet gases). The parametric analysis on the effects of the particle species and concentrations on CO2 bubble absorption rate is carried out. The particle concentration ranges from 0.005 to 0.5 vol%. It is found that the CO2 absorption rate is enhanced up to 4.5% at 0.01 vol% of Al2O3/methanol nanofluids at 20 °C, and 5.6% at 0.01 vol% of SiO2/methanol nanofluids at −20 °C, respectively.

The study on the critical heat flux and pool boiling heat transfer coefficient of binary nanofluids (H2O/LiBr + Al2O3) / Jung-Yeul Jung in International journal of refrigeration, Vol. 36 N° 3 (Mai 2013) 

Public ISBD [article]  in International journal of refrigeration > Vol. 36 N° 3 (Mai 2013) . - pp. 1056–1061 Titre : The study on the critical heat flux and pool boiling heat transfer coefficient of binary nanofluids (H2O/LiBr + Al2O3) Titre original : Etude sur le flux thermique critique et le coefficient de transfert de chaleur des nanofluides binaires (H2O/LiBr + Al2O3) lors de l'ébullition libre Type de document : texte imprimé Auteurs : Jung-Yeul Jung, Auteur ; Eung Surk Kim, Auteur ; Youngsuk Nam, Auteur Année de publication : 2013 Article en page(s) : pp. 1056–1061 Note générale : Refrigeration Langues : Anglais (eng) Mots-clés : Binary  mixture;  Particles;  Heat  flux;  Heat  transfer  coefficient;  Pool  boiling Résumé : In this study, we measured the critical heat flux (CHF) and boiling heat transfer coefficient of H2O/LiBr-based binary nanofluids. By using the PVA (polyvinyl alcohol) as a stabilizer, Al2O3 nanoparticles could be stably dispersed in H2O/LiBr. The plate copper heater (10 × 10 mm2) is used as the boiling surface. The concentration of nanoparticle varies 0–0.1 vol%, dispersed in H2O/LiBr solutions (3, 7 and 10 wt% of LiBr). The results show that the boiling heat transfer coefficient of the binary nanofluids becomes lower than that of the base fluid as the concentration of nanoparticles increases while CHF of it becomes higher. We obtained an enhanced CHF of ∼48.5% (compared to the base fluid) with the 0.1 vol% Al2O3 in 10 wt% LiBr aqueous solution.
