AbstractTaking into account the effect of velocity profiles of the continuous phase in interstices of drops, drag coefficient and relative motion correlations for dispersed liquid-liquid two-phase flow in absence of mass transfer were developed in terms of the pseudo-fluid concept based on the simple similarity criteria and the mixture viscosity model suggested by Ishii and Zuber. The present model was compared with the experimental data from five different sources and also with seven other pertinent correlations available in literature. Fairly good predictions were obtained under wide ranges of the dispersed phase holdup and Reynolds number. The validity of the present model has also been checked against the experimental slip velocity data and holdup data obtained in a Karr reciprocating plate extraction column by the author of the present paper and satisfactory agreement is achieved. The results show that the equations of the motion of a multi-droplet system can be formulated in a form identical with those for a single drop system in terms of the pseudo-fluid concept, which simplifies the description of the characteristics of the dispersed liquid-liquid two phase flow in extraction columns.
