Effects of mass transfer on drop size and interfacial tension in drop formation.

The mass transfer rate during drop formation was measured by an experimental method in which a continuousphase adder was used. The continuous phase was circulated in the column counter-currently to the drop phase, and the distance between the nozzle tip and the drop collector was kept short. From the data obtained in four binary systems a best drop size prediction model was chosen, and the model was applied to four ternary systems for obtaining interfacial tension during mass transfer. The drop size was correlated in terms of solute molar flux, nozzle size, and density difference between the dispersed and continuous phases. Also, the interfacial tension change was correlated with solute molar flux. The two correlation equations gave good predictability for the systems in this study.
