Effect of dispersed-phase viscosity on the maximum stable drop size for breakup in turbulent flow

Abstract

A formula for the maximum stable drop size has been derived theoretically, by taking into consideration the effect of the dispersed-phase viscosity. The derived formula indicates that the controlling factors of the maximum stable drop size are the Weber Number and the viscosity group which is defined as the ratio of the viscous stress to the stress of interfacial tension. The validity of the formula was confirmed experimentally over a wide range of dispersed-phase viscosity. © 1977, The Society of Chemical Engineers, Japan. All rights reserved.
