Second‐Law Analysis of Mini/Micro Counterflow Parallel‐Plate Heat Exchangers: Optimizing Effectiveness by Minimizing Wall Entropy Production

Heat Transfer, Volume 54, Issue 7, Page 4536-4554, November 2025.
ABSTRACT We present an analytical and numerical study of the entropy production rate in laminar counterflow parallel‐plate heat exchangers, aiming to investigate the interplay between multidimensional wall conduction, entropy production, and the optimum wall conductivity that leads to maximum effectiveness.

Numerical Analysis of Local Thermal Non‐Equilibrium Experiments Reveals Conceptual Regimes of Grain‐Scale Heat Transport

Water Resources Research, Volume 61, Issue 11, November 2025.
Abstract Modeling heat transport in saturated porous media typically assumes local thermal equilibrium (LTE) conditions, though this assumption lacks justification. Recent work has revealed local thermal non‐equilibrium (LTNE) effects for groundwater flow conditions, which standard one‐dimensional analytical and numerical models fail to capture ...

Crafting agency in a host community: Accessing and participating in the English higher education sector by Ukrainian refugees

British Educational Research Journal, Volume 51, Issue 5, Page 2401-2425, October 2025.
Abstract Following Russia's launch of a full‐scale war against Ukraine in 2022, scholarship has not yet addressed how Ukrainian refugees in England have been navigating the challenges of developing their agency in pursuing opportunities to participate in the higher education (HE) sector.

Dynamics of Bio‐Convection Two‐Phase Nanofluid Flow in an Entropy‐Optimized Non‐Newtonian Model With Nonlinear Thermal Radiation and Electromagnetic Effects

Energy Science &Engineering, Volume 13, Issue 10, Page 4955-4972, October 2025.
ABSTRACT The study of nanofluids has attracted significant attention due to their superior thermophysical properties, making them ideal for thermal transport in engineering and biomedical applications. Motivated by these capabilities, this study develops a novel three‐dimensional mathematical model for electrically conducting Sutterby nanofluids ...

Peers, equals, and jurors: New data and methods on legal equality in Leveller thought

American Journal of Political Science, Volume 69, Issue 4, Page 1505-1518, October 2025.
Abstract We consider the Levellers' conception of equality relative to their contemporaries during the Civil War(s) period. We compile a corpus of hundreds of seventeenth−century pamphlets and combine this with novel word embedding techniques trained on millions of Early Modern English documents to make statements about word “meanings.” We focus on ...
