A novel numerical technique for simulating interfacial gravity waves is considered. The model comprises an immiscible, binary fluid lattice Boltzmann model incorporating a gravitational interaction and simulates two immiscible, viscous fluids of different densities with a sharp interface between them. The model is described and the accuracy of the technique is considered. Simulation results are...

In this paper, we propose a new fluid-fluid collision model for particle-based immiscible fluid animation. Our model consists of two components, namely, collision detection and collision response. An interesting feature is that our model not only can prevent immiscible fluids from mixing with each other, but also can allow one fluid to run through or to wrap around another fluid. The model is v...

Large scale lattice Boltzmann simulations are utilized to investigate spinodal decomposition and structuring effects in binary immiscible and ternary amphiphilic fluid mixtures under shear. We use a highly scalable parallel Fortran 90 code for the implementation of the simulation method and demonstrate that adding surfactant to a system of immiscible fluid constituents can change the mixture’s ...

We report a microfluidic approach for one-step fabrication of polyelectrolyte microcapsules in aqueous conditions. Using two immiscible aqueous polymer solutions, we generate transient water-in-water-in-water double emulsion droplets and use them as templates to fabricate polyelectrolyte microcapsules. The capsule shell is formed by the complexation of oppositely charged polyelectrolytes at the...

Experiments in which vortex rings of one immiscible liquid are created in another from drops falling from rest under gravity are presented and interpreted. These rings are associated with circulations generated by viscosity and, unlike classical vortex rings which occur in miscible liquids at high Reynolds numbers, they can exist even at very low Reynolds numbers. Since the rings do not diffuse...

From molecular dynamics simulations on immiscible flows, we find the relative slipping between the fluids and the solid wall everywhere to follow the generalized Navier boundary condition, in which the amount of slipping is proportional to the sum of tangential viscous stress and the uncompensated Young stress. The latter arises from the deviation of the fluid-fluid interface from its static co...

The thermodynamic phase diagram of an agrochemical active ingredient (AI) in water and acetone was determined using array process analytical technology (PAT) tools equilibrium experiments. This ternary system found to separate into multiple liquid phases at certain temperatures concentrations (oiling out). Furthermore, agglomeration the solid particles observed specific conditions. Signals from...

We study the correlated dynamics of few interacting bosonic impurities immersed in a one-dimensional harmonically trapped environment. The mixture is exposed to time-dependent impurity-medium interaction pulse moving it across relevant phase-separation boundary. For modulation frequencies smaller than trapping one, system successively transits through miscible and immiscible phases according dr...

Abstract Several authors have shown promising results using Ti and Mg to develop materials that combine the benefits of these two metals, such as their low density absence harmful second phases, which makes them attractive for aerospace biomedical applications well hydrogen storage. However, titanium magnesium are almost immiscible there great differences in processing temperatures metals. With...
