DROP SIZE DISTRIBUTION IN A LIQUID-LIQUID PHASE MIXING VESSEL

The drop size distribution in a vessel is decided by the mutual relation between energy dissipation rate, residence time of drops at a certain location, break-up rate of drops and coalescence rate of drops. Experimental results so far, however, leave us far from an understanding of the precise mutual relation. Accordingly, the authors have made correlative equations representing the drop-size distribution under various mixing conditions. It is observed in this study that a combination of three normal distribution curves gives a good fit for the volumetric drop-size distribution and that the number distribution of drops is also given by a combination of two normal distribution curves.
