Modeling of gas-water transport in the porous transport layer of a proton exchange membrane electrolyzer

In this work, the mechanism of gas invasion into a saturated thin porous medium, specifically the Porous Transport Layer used in a Proton Exchange Membrane electrolyzer, is investigated. The phase-field model based on the Cahn-Hilliard theory is employed to capture the dynamics o...

Experimental investigation of surface inclination effects on ablation of a solid impacted by a hot liquid jet

In sodium-cooled fast reactors (SFRs), the potential consequences of a severe accident with core meltdown are now considered during the reactor design phase. Such events lead to the formation of a corium , a radioactive mixture of molten nuclear fuel and structural materials. Two...

Integrated experimental and modeling study of air psychrometry and velocity effects on cooling pad performance

This study presents a combined experimental and modeling investigation of cellulose-based evaporative cooling pads, focusing on the synergistic effects of inlet air psychrometric conditions and air velocity on cooling performance. Unlike conventional studies that examine temperat...

Influence of atomic vacancies on the electronic and mechanical properties of two-dimensional <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:msub> <mml:mi>AsBiSe</mml:mi> <mml:mn>3</mml:mn> </mml:msub> </mml:math> monolayers

Using first-principles calculations and ab initio molecular dynamics, we investigate the formation of atomic vacancies in the monolayer ${\mathrm{AsBiSe}}_{3}$ and its consecutive effect on electronic and mechanical properties. The calculated formation energies reveal that Se vac...
