Optimal Nanoparticle Size in SiO₂/Al₂O₃‐Water Nanofluids for Enhancing Intercooler Thermal Enhancement: A Conjugate Heat Transfer Study

open access: yesEnergy Science &Engineering, Volume 14, Issue 3, Page 1387-1397, March 2026.
The simulation shows that the comprehensive heat transfer effect of using nanofluids as cooling liquid is greater than 1.30 nm SiO2/water and 40 nmAl2O3/water nanofluids have the best heat transfer enhancement effect, while all nanofluids of 30 nm Al2O3/water have the best heat transfer enhancement effect.

Experimental and Numerical Study on Enhancing the Performance of a Stepped Solar Still Using Porous Sponge Materials

open access: yesEnergy Science &Engineering, Volume 14, Issue 3, Page 1456-1473, March 2026.
Three designs were built and tested: a single‐slope still, a six‐stepped still, and a six‐stepped still with 5 mm sponge sheets. The novelty lies in fixing porous sponge sheets to the vertical faces of the steps. Yield of freshwater and instantaneous efficiency were determined in various combinations, that is, base, stepped, and stepped‐cum‐sponge ...

A Mathematical Model for Two‐Phase Flow in Confined Environments: Numerical Solution and Validation

open access: yesInternational Journal for Numerical Methods in Fluids, Volume 98, Issue 3, Page 306-320, March 2026.
We present a numerical framework based on the Cahn‐Hilliard‐Navier‐Stokes (CHNS) model to simulate biphasic flow in confined environments. After deriving the mathematical model, we develop the weak form of the system of PDEs using a pedagogical approach to enable its implementation in FEniCS.

Analysis of Turbulent Modeling for Free‐Surface Flows Using a Hybrid RANS‐LES Model and Particle‐Based Moving Particle Semi‐Implicit Method

open access: yesInternational Journal for Numerical Methods in Fluids, Volume 98, Issue 3, Page 321-347, March 2026.
A hybrid RANS‐LES turbulence model adapted for the Moving Particle Semi‐implicit method is employed to investigate a turbulent free surface flow. A method based on the cell‐linked list is proposed to speed up the nearest wall search for the turbulence model.

Extended Kelvin–Voigt Model for Simulating Thermally Accelerated Creep in Fine‐Grained Soils

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 4, Page 1843-1854, March 2026.
ABSTRACT The subsurface undergoes temperature variations in many situations due to anthropogenic and natural causes, which strongly influence the long‐term behavior of soils. These phenomena can involve temperature anomalies in the ground across distances of a few meters, as in the case of nuclear waste repositories, to distances encompassing entire ...
