Multiphase immiscible flow through porous media
… for multiphase flow through soil involving three immiscible fluids: namely air, water, and an organic fluid. A variational method is employed for the finite element formulation corresponding to the coupled differential equations governing the flow of the three fluid phase porous medium system with …

The condensation of vapours of binary immiscible liquids
… form of the Nusselt equation. For the binary immiscible systems the heat transfer coefficients decrease as the temperature difference increases, with the oxidised copper surface giving higher coefficients than the gold. These differences are attributed to the two observed fundamental …

Microstructural evolution of silicate immiscible liquids in solidifying ferrobasalts
… homogeneously nucleated droplets dispersed in an immiscible Si-rich liquid, together with droplets heterogeneously nucleated on plagioclase, magnetite, and pyroxene. Heterogeneous nucleation is likely promoted by localised compositional heterogeneities around growing crystals. The equilibrium …

Compatibilisation and stabilisation of immiscible polymer blends by reactive processing
The main objectives of this research were to develop optimised chemical compositions and reactive processing conditions for grafting a functional monomer maleic anhydride (MA) in polypropylene (PP), ethylene propylene diene monomer (EPDM) and mixtures of PP-EPDM, and to optimise synthetic routes …

Phase and Microstructural Stability in Immiscible Binary Alloys Under Irradiation
In the experimental part, we investigate the microstructures resulting under ion-beam mixing in Ag-Cu multilayers. We find that, regardless of the irradiation temperature, extensive grain growth takes place. In the regime when thermal decomposition is in dynamic balance with irradiation mixing, …

Severe plastic deformation in highly immiscible copper alloys: self-organization
Severe plastic deformation (SPD) techniques such as equal channel angular pressing (ECAP), high pressure torsion (HPT), high energy ball milling (BM), accumulative roll bonding (ARB), are well known to refine the microstructures of metals and alloys into non-equilibrium states with nanometer-size …

Amorphization and De-vitrification in Immiscible Copper-Niobium Alloy Thin Films
While amorphous phases have been reported in immiscible alloy systems, there is still some controversy regarding the reason for the stabilization of these unusual amorphous phases. Direct evidence of nanoscale phase separation within the amorphous phase forming in immiscible Cu-Nb alloy thin films …

NUMERICAL ANALYSIS OF CO-FLOWING IMMISCIBLE LIQUIDS IN CO-AXIAL MICROTUBES
This research developed dimensionless correlations, based on the numerical simulations, for the boundaries between the dripping, transition and jetting regimes. Additional correlations are also developed for the radius and formation frequency of disperse droplet in the dripping regime and the …

Immiscible displacement of trapped oil through experimental and data mining techniques.
… potential and competitiveness of gases used in immiscible gas-enhanced oil recovery (EOR) processes. Methane (CH4), Nitrogen (N2), Air (21%O2/N2) and Carbon Dioxide (CO2) are some of the gases injected in reservoirs to displace trapped oil from reservoir pores. The EOR screening process has been …

Heat Transfer and Hydrodynamics of Miscible/Immiscible Systems in Microchannel Devices
… both the single-phase/miscible and multiphase/immiscible systems have been studied. This work starts with the effect of the nanoparticles (NPs) on heat transfer enhancement in microchannel devices. The NPs non-homogeneous distribution and their impact on the heat removal and the friction factor …

Transport of Molecular Cargoes By Coordination Cages Between Immiscible Liquid Phases
Directed transport of materials against chemical potential gradients is a fundamental feature of living systems, underpinning processes that range from transport through cell membranes to neurotransmission. The development of artificial active cargo transport could enable new modes of chemical …

Modeling the Dissolution of Immiscible Contaminants in Groundwater for Decision Support
Predicting the dissolution rates of immiscible contaminants in groundwater is crucial for developing environmental remediation strategies, but quantitative modeling efforts are inherently subject to multiple uncertainties. These include unknown residual amounts of non-aqueous phase liquids (NAPL) …

Direct contact heat transfer between an evaporating fluid and an immiscible liquid
An investigation has been conducted into the process of cooling water by the evaporation of droplets of isopentane in direct contact. The research has potential industrial application to a pickling acid recovery crystalliser. In order to minimise industrial equipment size a counter current flowing …
