Liquid Jet Instability and Atomization in a Coaxial Gas Stream
TL;DR: In this article, an overview of the near and far-field breakup and atomization of a liquid jet by a high speed annular gas jet is presented, and various regimes of liquid jet breakup are discussed in the parameter space of the liquid Reynolds number, the aerodynamic Weber number, and the ratio of the momentum fluxes between the gas and the liquid streams.

On the breakup of an air bubble injected into a fully developed turbulent flow. Part 1. Breakup frequency
TL;DR: In this article, a phenomenological model is proposed showing the existence of two distinct bubble size regimes, i.e., 1.3D and 1.6D. The model is shown to be in good agreement with measurements performed over a wide range of bubble sizes and turbulence intensities.
Journal ArticleDOI
An Updated Review on Suspension Polymerization
TL;DR: Most of the experimental information in this review is related to the styrene/divinylbenzene copolymerization system, although the ideas and models are not exclusive to this system.
Journal ArticleDOI
On the breakup of an air bubble injected into a fully developed turbulent flow. Part 2. Size PDF of the resulting daughter bubbles
TL;DR: In this article, the authors proposed a statistical model to describe the bubble size probability density function of the daughter bubbles resulting from the shattering of a mother bubble of size D0 immersed in a fully developed turbulent water flow.

Description of interaction processes in agitated liquid-liquid dispersions
TL;DR: In this paper, phenomenological models are proposed to describe drop breakup and coalescence in a turbulently agitated liquid-liquid dispersion, and the breakage and rate functions are developed and used to solve the general population balance equation describing drop interactions in a continuous flow vessel.
Journal ArticleDOI
Breakage and coalescence models for drops in turbulent dispersions
TL;DR: In this article, two-step mechanisms are considered for both the breakage and coalescence models, and a probability density is proposed based on the energy requirements for the formation of daughter drops.

Relaxation and breakup of an initially extended drop in an otherwise quiescent fluid
Howard A. Stone,L. G. Leal +1 more
TL;DR: In this paper, a detailed numerical investigation of the end-pinching behavior reported in a previous experimental study is presented. And the numerical procedure is used to study the simultaneous development of capillary-wave instabilities at the fluid-fluid interface of a very long, cylindrically shaped droplet with bulbous ends.

Drop breakup in turbulent stirred‐tank contactors. Part I: Effect of dispersed‐phase viscosity
TL;DR: In this article, the extent to which dispersed-phase viscosity influences equilibrium mean drop size and drop size distribution at constant interfacial tension is determined for dilute suspensions by dispersing silicone oils of various viscosities grades in water.

On the behaviour of liquid dispersions in mixing vessels
TL;DR: In this article, the authors apply the theoretical concepts of local isotropy to explain the behavior of liquid in liquid dispersions, subjected to turbulent agitation, and compare the influence of turbulence on both breakup and coalescence of individual droplets.
