Enslaved phase-separation fronts in one-dimensional binary mixtures.

Phase separation of incompressible binary fluids with Lattice Boltzmann Methods

We introduce new versions of lattice Boltzmann methods (LBM) for incompressible binary mixtures where fluctuations of total density are inhibited. As a test for the improved algorithms we consider the problem of phase separation of two-dimensional binary mixtures quenched from a disordered state into the coexistence region. We find that the stability properties of LBM are greatly improved. The ...

Experimental and Theoretical Study of Phase Equilibria in Aqueous Mixtures of Lactic Acid with Benzyl Alcohol and p-Xylene at Various Temperatures

Liquid-liquid equilibria for the (water + lactic acid + benzyl alcohol or p-xylene) ternary systems were investigated at atmospheric pressure and in the temperature range from 298.15-318.15 K. The studied systems exhibit two types of liquid-liquid equilibrium (LLE) behavior. The system consisting of benzyl alcohol displays type-1 LLE behavior, while a type-2 behavior is exhibited by th...

Separation-Based Adsorption of H2 from Binary Mixtures inside Single, Double, Triple Walled Boron-Nitride Nanotubes: A Grand- Canonical Monte-Carlo Study

This study investigates the separation based on adsorption of the binary gas mixture of hydrogen withbiogas (gases: CO2, CH4, O2, N2) and inert gases (gases: He, Ne, and Ar) using single-walled ((7,7), (15,15),(29,29), (44,44), (58,58) and (73,73) SWBNNTs), double-walled ((11,11)@(15,15), (7,7)@(22,22) DWBNNTs)and triple walled ((8,8)@(11,11)@(15,15) and (7,7)@(15,15)@(22,22) ...

Group Contribution Method for Predicting the Phase Behavior of Binary Mixtures Containing Carbon Dioxide

Scale invariance in coarsening of binary and ternary fluids.

Phase separation in binary and ternary fluids is studied using a two-dimensional lattice gas automata. The lengths given by the the first zero crossing point of the correlation function and the total interface length is shown to exhibit power law dependence on time. In binary mixtures, our data clearly indicate the existence of a regime having more than one length scale, where the coarsening pr...
