Abstract
The effect of continuous-phase viscosity on the drop sizes of liquid-liquid dispersions in agitated vessels operated batchwise was experimentally examined. The systems studied were kerosene dispersed in aqueous glycerol (3.6 cP < µc < 223.1 cP) and mineral oil dispersed in aqueous glycerol (3.5 cP < µc < 122.6 cP) for impeller Reynolds numbers ranging from 358 to 23467. Photomicrographic study indicates that the effect of continuous-phase viscosity on the drop size distribution is most pronounced for systems of high dispersed-phase viscosities. A logarithmic plot of the Sauter mean diameter as a function of the impeller speed is a straight line, the slope of which varies with the continuous-phase viscosity. The slope increases, reaches a maximum, and then decreases with increasing continuous-phase viscosity.
