Abstract. The stirring of immiscible liquids is considered, and the effect of impeller geometry on the dynamic equilibration of the emulsion and on the maximum drop size is analyzed. The dissipation rate of turbulent energy in the wake of an impeller blade is estimated. Download to read the full article text.
