Kinetics of drop breakup during emulsification in turbulent flow
Systematic set of emulsification experiments is performed to elucidate the role of several factors, which control the process of drop breakup during emulsification in turbulent flow. As starting oil-water premixes we use emulsions containing monodisperse oil drops, which are generated by the method of membrane emulsification. By passing these premixes through a narrow-gap homogenizer working in...
متن کاملThermal delay of drop coalescence
We present the results of a combined experimental and theoretical study of drop coalescence in the presence of an initial temperature difference 1T0 between a drop and a bath of the same liquid. We characterize experimentally the dependence of the residence time before coalescence on 1T0 for silicone oils with different viscosities. Delayed coalescence arises above a critical temperature differ...
متن کاملDrop coalescence and liquid flow in a single Plateau border.
We report a comprehensive study of the flow of liquid triggered by injecting a droplet into a liquid foam microchannel, also called a Plateau border. This drop-injected experiment reveals an intricate dynamics for the liquid redistribution, with two contrasting regimes observed, ruled either by inertia or viscosity. We devoted a previous study [A. Cohen et al., Phys. Rev. Lett. 112, 218303 (201...
متن کاملDrop-breakage in Agitated Liquid-liquid Dispersions
Experimental data from batch vessels on cumulative volumetric drop-size distributions at various times are shown to yield useful information on probabilities of droplet-breakup as a function of drop-size. Such information is sufficient for a priori prediction of drop-sizes in agitated dispersions in batch and continuous vessels. It may also be useful in predicting heat and/or mass transfer in l...
متن کاملModel for drop coalescence in a locally isotropic turbulent flow field.
The proposed model views drop coalescence in a turbulent flow field as a two-step process consisting of formation of a doublet due to drop collisions followed by coalescence of the individual droplets in a doublet due to the drainage of the intervening film of continuous phase under the action of colloidal (van der Waals and electrostatic) and random turbulent forces. The turbulent flow field w...
