Fluctuation-induced dynamics of multiphase liquid jets with ultra-low interfacial tension Fascinating jet morphologies are observed in perturbation-induced dripping-to-jetting transition in multiphase liquid systems characterized by ultra-low interfacial tensions

Smoothed dissipative particle dynamics model for mesoscopic multiphase flows in the presence of thermal fluctuations.

Thermal fluctuations cause perturbations of fluid-fluid interfaces and highly nonlinear hydrodynamics in multiphase flows. In this work, we develop a multiphase smoothed dissipative particle dynamics (SDPD) model. This model accounts for both bulk hydrodynamics and interfacial fluctuations. Interfacial surface tension is modeled by imposing a pairwise force between SDPD particles. We show that ...

A Microfluidic Platform for the Production of Monodisperse Ultralow Interfacial Tension Oil Droplets in Water

We present a novel microfluidic approach for the generation of monodisperse oil droplets in water with ultra-low interfacial tensions. Using an oil-water-surfactant formulation under conditions close to the microemulsion phase transition, we actively controlled the surface tension at the liquid-liquid interface within the microfluidic device in order to produce monodisperse droplets. These drop...

Gas-liquid Relative Permeability Estimation in 2D Porous Media by Lattice Boltzmann Method: Low Viscosity Ratio 2D LBM Relative Permeability

This work is a primary achievement in studying the CO2 and N2–oil systems. To predict gas-liquid relative permeability curves, a Shan-Chen type multicomponent multiphase lattice Boltzmann model for two-phase flow through 2D porous media is developed. Periodic and bounce back boundary conditions are applied to the model with the Guo scheme for the external body force (i.e.,...

All-aqueous multiphase microfluidics.

Immiscible aqueous phases, formed by dissolving incompatible solutes in water, have been used in green chemical synthesis, molecular extraction and mimicking of cellular cytoplasm. Recently, a microfluidic approach has been introduced to generate all-aqueous emulsions and jets based on these immiscible aqueous phases; due to their biocompatibility, these all-aqueous structures have shown great ...
