Drop break-up and coalescence in intermittent turbulent flow

Wioletta Podgórska , Jerzy Robert Bałdyga

Abstract

Effects of turbulent agitation on the transient drop size distributions are considered. Drop dispersion and coalescence phenomena depend on the fine-scale properties of turbulence, including its intermittency. A multifractal formalism describes intermittency and is used to derive drop break-up and coalescence functions for drops, whose diameter falls within the inertial subrange of turbulence. The transient drop size distributions are predicted by solving the population balance equation for the single-circulation-loop model of agitated tank; the predictions are in good agreement with reported experimental data.
