Separation of a binary liquid mixture in compound system: Fluid–porous–fluid

On the unsteady-state species separation of a binary liquid mixture in a rectangular thermogravitational column.

This paper investigates the unsteady-state species segregation of binary liquid mixtures in rectangular thermogravitational columns. The analysis leads to a procedure to obtain both molecular and thermal diffusion coefficients from transient separation measurements. Two models are presented: first, an ideal model where buoyancy only depends on temperature and second, a general model where buoya...

Polymerization-induced phase separation in a liquid-crystal-polymer mixture.

Temporal fluctuations in a turbulently stirred binary liquid mixture.

Liquid-vapor phase behavior of a symmetrical binary fluid mixture

Using Monte Carlo simulation and mean-field calculations, we study the liquid-vapor phase diagram of a square-well binary fluid mixture as a function of a parameter d measuring the relative strength of interactions between particles of dissimilar and similar species. The results reveal a rich variety of liquid-vapor coexistence behaviors as d is tuned. Specifically, we uncover critical end poin...

Low-temperature phase separation of a binary liquid mixture in porous materials studied by cryoporometry and pulsed-field-gradient NMR.

The low-temperature liquid-liquid phase separation of the partially miscible hexane-nitrobenzene mixture imbibed in porous glasses of different pore sizes from 7 to 130 nm has been studied using 1H NMR (nuclear magnetic resonance) cryoporometry and pulse field gradient NMR methods. The mixture was quenched below both its upper critical solution temperature (T(cr)) and the freezing point of nitr...
