Influence of speed on the internal flow characteristics of a multiphase pump based on a coupled CFD-PBM model

Frontiers in Physics
Under the influence of the characteristic behavior of the bubbles, the flow pattern in the multiphase pump suffers a serious deterioration and the pressurization performance is significantly reduced. In order to be more close to the engineering practice,

Indium‐Mediated Glue‐Like Interlayer Enables Stable High‐Capacity Flexible Sodium Metal Batteries

Advanced Materials, EarlyView.
A three‐dimensional Na‐In‐S/Cu composite interlayer is constructed on a flexible current collector via an In‐mediated in situ reaction. Featuring abundant Na nucleation sites and a low diffusion barrier, this interlayer enables rapid and uniform Na deposition.

Multiphase Relaxation Dynamics at the μm‐to‐cm Scale During Storage of Gases in Rocks: A Micro‐CT Study on Homogeneous and Layered Sandstones

Water Resources Research
Recent work suggests that upscaling multiphase flow requires averaging capillary fluctuations in both space and time. This motivates the need to determine the representative time and length scales of multiphase flow and how they are interrelated ...

Engineering CO2 Reduction Pathways via Alloy‐Support Interactions in Li‐CO2 Batteries

Advanced Materials, EarlyView.
Alloy‐support interactions in RuCu/NC induce interfacial charge redistribution and shift d‐band centers, steering CO2 reduction from Li2CO3 to metastable Li2C2O4. This pathway engineering lowers the rate‐determining barrier and suppresses carbonate formation, enabling high discharge voltage (3.23 V) in Li‐CO2 batteries with reduced overpotential (0.50 ...

Thermo-hydro-mechanical-air coupling finite element method and its application to multi-phase problems

Journal of Rock Mechanics and Geotechnical Engineering, 2014
In this paper, a finite element method (FEM)-based multi-phase problem based on a newly proposed thermal elastoplastic constitutive model for saturated/unsaturated geomaterial is discussed. A program of FEM named as SOFT, adopting unified field equations
