In the conventional multiphase flow, immiscible having a liquid-liquid interface, two liquids are merged in flow path to form interface. The two-phase separation mixed solution has property of phase-separating from one phase phases by changing temperature/pressure, and phase-separates into upper lower batch-type vessel. By while sending this micro-space region, interface is formed obtained. Thi...

In the last few decades, theoretical and experimental studies of glass-forming liquids have revealed presence universal regularities in viscosity-temperature data. present work, we propose a viscosity model for scaling description A feature this is only two adjustable parameters high accuracy data approximation by wide temperature range. The basis an original scale. Within obtain transformed An...

Two-fluid Dean vortex flow in a coiled pipe with vanishing torsion, and its effect on the mass transfer through the liquid–liquid interface of two immiscible fluids are studied numerically. The liquids are stratified by gravity, with the denser one occupying the lower part of the pipe. The Navier–Stokes equations in both fluid layers are solved numerically by the finite volume method. The resul...

the present investigation entails a procedure by which the surface tension and viscosity of liquids could be redicted.to this end, capillary experiments were performed for porous media by utilizing fifteen different liquids and powders. the time of capillary rise to a certain known height of each liquid in a particular powder was recorded. two artificial neural networks (anns) were designed and...

Junctions of one-dimensional systems are great interest to the development synthetic materials that harbor topological phases. We study a junction three gapless spin-1 chains described by $\mathrm{SU}{(2)}_{2}$ Wess-Zumino-Wittten model and coupled exchange chiral three-spin interactions. show fixed point appears as special on transition line separating two regimes open boundary conditions, cor...

We use molecular dynamics simulations to study phase separation of a 50:50 (by volume) fluid mixture in a confined and curved (Taylor-Couette) geometry, consisting of two concentric cylinders. The inner cylinder may be rotated to achieve a shear flow. In nonsheared systems we observe that, for all cases under consideration, the final equilibrium state has a stacked structure. Depending on the l...

We derive a closed equation for the empirical concentration of colloidal particles in the presence of both hydrodynamic and direct interactions. The ensemble average of our functional Langevin equation reproduces known deterministic Dynamic Density Functional Theory (DDFT) [M. Rex and H. Löwen, "Dynamical density functional theory with hydrodynamic interactions and colloids in unstable traps," ...

The production from biomass of chemicals and fuels by fermentation, biocatalysis, and related techniques implies energy-intensive separations of organics from relatively dilute aqueous solutions, and may require use of hazardous materials as entrainers to break azeotropes. We consider the design feasibility of using ionic liquids as solvents in liquid-liquid extractions for separating organic c...
