Nonideal behavior during complete dissolution of organic immiscible liquid

Dissolution of a liquid microdroplet in a nonideal liquid-liquid mixture far from thermodynamic equilibrium.

A droplet placed in a liquid-liquid solution is expected to grow, or shrink, in time as approximately t;{1/2}. In this Letter, we report experimental evidence that when the composition in the interface is far from thermodynamic equilibrium due to the nonideality of the mixture, a droplet shrinks as approximately t. This scaling is due to the coupling between mass and momentum transfer known as ...

Path Dissolution: A Strongly Complete

Dissolution Dynamics of Liquid/Liquid Binary Mixtures Within a Micromodel

We report optical observations of the dissolution behaviour of glycerol/water, soybean oil/hexane, and isobutyric acid (IBA)/water binary mixtures within a glass micromodel built as a 2D regular network of capillary tubes with diameter of 0.2 mm. The micromodel is initially filled with solute and then is horizontally immersed into a thermostatic solvent-filled bath. The micromodel is open at it...

Bench-scale Investigations on Vibratory Mobilization of Immiscible Liquid Ganglia

Prior investigations by the principal author evaluated the feasibility of mobilizing non-aqueous phase liquid (NAPL) ganglia by inducing vibrations in a soil-NAPL-water medium. In this paper, results from bench-scale experiments are reported to provide a practical understanding of the impact of vibrations (induced with a probe-type vibrator) on relative density of the medium and on the ganglia ...

Boiling Heat Transfer Characteristics of Immiscible Liquid Mixtures

Cooling technology becomes more important because of the increase in heat generation density of semiconductor chips. Boiling and two-phase flow is expected as one of the most effective methods to cool the electronic devices because of its superior heat transfer characteristics. Because the boiling heat transfer depends on the selection of coolant, the development of liquid mixtures and their co...
