Flow of Two Immiscible Couple Stress Fluids between Two Permeable Beds

Journal of Applied Fluid Mechanics, 2016
The paper deals with the flow of two immiscible couple stress fluids between two homogeneous permeable beds. The flow is considered in two zones: zone I and II contain free flow of two immiscible couple stress fluids between two permeable porous beds ...

Predicting flows through microfluidic circuits with fluid walls

Microsystems & Nanoengineering, 2021
The aqueous phase in traditional microfluidics is usually confined by solid walls; flows through such systems are often predicted accurately. As solid walls limit access, open systems are being developed in which the aqueous phase is partly bounded by ...

Heteroatom‐Mediated Covalent Organic Framework Membranes With Nitrogen‐Enriched Nanochannels for Efficient Desalination

Advanced Science, EarlyView.
Heteroatom precursor engineering serves as a molecular‐level strategy to tailor hydrazide monomer reactivity and diffusion kinetics, enabling controlled assembly of highly crystalline COF membranes with ultramicroporous channels. The nitrogen‐enriched nanochannels deliver high water/ion selectivity via simultaneous water transport acceleration and ion ...

Decoding Interfacial Polymerization Through Steady Amine Delivery and Real‐Time QCM‐D Monitoring

Advanced Science, EarlyView.
We combine steady amine delivery with in situ quartz crystal microbalance with dissipation to track interfacial polymerization in real time. The platform resolves three kinetic regimes: pre‐gelation oligomerization, post‐gelation aggregation and network growth, and diffusion‐limited film evolution.

Mixed convective flow of immiscible fluids in a vertical corrugated channel with traveling thermal waves

Journal of King Saud University: Engineering Sciences, 2014
Fully developed laminar mixed convection in a corrugated vertical channel filled with two immiscible viscous fluids has been investigated. By using a perturbation technique, the coupled nonlinear equations governing the flow and heat transfer are solved.

Deciphering Electrochemical Generation, Transport, and Reactivity of Hydrogen Species in the Electrochemical Palladium Membrane Reactor

Advanced Science, EarlyView.
This study elucidates hydrogen transport and reaction mechanisms in ePMR using 1‐hexyne hydrogenation as a model reaction. Hydrogen transport operates via dual pathways involving hydrogen atom permeation and H2‐mediated re‐dissociation on secondary metal layers.

Dynamic wettability alteration in immiscible two-phase flow in porous media: Effect on transport properties and critical slowing down

Frontiers in Physics, 2015
The change in contact angles due to the injection of low salinity water or any other wettability altering agent in an oil-rich porous medium is modeled by a network model of disordered pores transporting two immiscible fluids.

Chloride‐Mediated Activation of Aluminum‐Alloyed Liquid Metal Anodes for Stretchable Asymmetric Energy Storage

Advanced Energy Materials, EarlyView.
A gallium‐centered cell pairs an aluminum‐alloyed GaIn anode with a GaOOH cathode in a chloride‐rich water‐in‐ionic‐liquid electrolyte. Chlorogallate ions dissolve the native oxide that normally seals the liquid metal, and preferentially reduce indium seeds to oxide‐free clusters on which gallium plates and strips reversibly.
