Abstract

A special type of a high pressure homogenizer valve was studied for the dispersive mixing of oil-in-water emulsions. Various hydrodynamic regimes and flow fields were identified using the commercial computational fluid dynamics (CFD) software ANSYS and, for each regime the stable droplet sizes were estimated. Experimental validation was carried out using a coarse emulsion containing 10 wt% sunflower oil stabilized with Pluronic F68, which was dispersed in the homogenizer apparatus. The change in oil droplet size with pressure drop is attributed to the high speedjet leaving the gap.
