Abstract

Using our new high magnification video technique and synchronised strobe light with semi-automatic image analysis, break-up of the dispersed phase will be studied in stirred batch and in continuous systems; and also pure coalescence, up to dispersed phase fractions just below those at which phase inversion occurs. This new technique allows very accurate data collection at such high concentrations over the whole size range at any location in the equipment; and much faster than previously. Using fluid dynamic concepts, the data will be used in a population balance framework to model break-up and coalescence as a function of drop size in pure systems and those modified by additives typical of the food industry to give different (mobile, semi-mobile or immobile) interfacial properties. The aim is to increase fundamental understanding so as to improve process and equipment design under batch and flowthrough conditions.
