Liquid – liquid two - phase flow patterns in a serpentine microchannel / P. S. Sarkar in Industrial & engineering chemistry research, Vol. 51 N° 13 (Avril 2012) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 51 N° 13 (Avril 2012) . - pp.5056–5066 Titre : Liquid – liquid two - phase flow patterns in a serpentine microchannel Type de document : texte imprimé Auteurs : P. S. Sarkar, Auteur ; Singh, K. K., Auteur ; K. T. Shenoy, Auteur Année de publication : 2012 Article en page(s) : pp.5056–5066 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Phase  flow  Microchannel Résumé : Liquid–liquid two-phase flow patterns in a serpentine glass microchannel have been studied using a camera with very high shutter speed. The phase system is equilibrated water−succinic acid−n-butanol system. Observed flow patterns have been classified into seven different types: slug flow, slug and droplet flow, droplet flow, unstable annular flow, annular flow, annular dispersed flow, and fully dispersed flow. Two different ways of introducing the aqueous and organic phases into the microchannel have been studied. Flow regime maps are presented and discussed. Voronoi diagrams of the flow regime maps are also presented.

Population balance modeling of liquid-liquid dispersions in homogeneous continuous-flow stirred tank / Singh, K. K. in Industrial & engineering chemistry research, Vol. 48 N° 17 (Septembre 2009) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 48 N° 17 (Septembre 2009) . - pp. 8121–8133 Titre : Population balance modeling of liquid-liquid dispersions in homogeneous continuous-flow stirred tank Type de document : texte imprimé Auteurs : Singh, K.

Shenoy, Auteur Année de publication : 2009 Article en page(s) : pp. 8121–8133 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Population  balance  modeling  Dilute  phosphoric  acid  n-paraffin  Tributyl  phosphate  Di-2-ethyl  hexyl  phosphoric  acid Résumé : This work presents population balance modeling to predict representative drop sizes and drop size distributions in dispersions of dilute phosphoric acid in a mixture of n-paraffin, tributyl phosphate, and di-2-ethyl hexyl phosphoric acid (D2EHPA) created in a continuous-flow stirred tank agitated with a top-shrouded pump-mix impeller having four trapezoidal blades. The stirred tank has been assumed to be homogeneous. Three population balance models, differing in droplet breakage rate models, have been evaluated. A part of the experimental data has been used to obtain the optimum values of the parameters of all the three models. The remaining part of the experimental data has been used to compare the models for their ability to predict the representative drop diameters and the number probability density distributions. On the basis of this comparison, the best model has been identified.
