KINETICS, MECHANISM, AND RESULTANT DROPLET SIZES OF THE AERODYNAMIC BREAKUP OF LIQUID DROPS

Abstract

A critical review of the breakup of liquids is given, with emphasis on liquid drops. Evidence is presented that the breakup is a rate process and hence must be considered from a time-dependent approach rather than from purely dimensionless parameters, such as Weber or Bond numbers. A theoretical model of the aerodynamic breakup of liquid drops is developed, postulating that the dual breakup mechanisms (bag and stripping) of liquid drops result from pressure and frictional drag on the drop. The derivation of a quantitative expression is presented, predicting aerodynamic breakup times of liquid drops as a function of the gas-flow properties and the physical properties of the drop. A quantitative expression is also developed that predicts the mass-mean diameter of droplets produced by aerodynamic breakup of the drop as a function of the gas-flow properties and physical properties of the drop.
