Investigation on tunnel stability considering pipe‐roof support with transparent soil technology

open access: yesDeep Underground Science and Engineering, EarlyView.
This study integrates transparent soil technology, 3D reconstruction and numerical simulation to captures the full‐field deformation of shield tunnel instability. Results demonstrate that pipe‐roof support enhances stability via the “soil‐arching barrier effect,” effectively restraining failure wedge development by extending stress transfer paths ...

Hydrogen‐Enriched Tri‐Fuel Combustion for Low‐Carbon Engines at Medium Engine Load: A Comprehensive CFD Analysis

open access: yesEnergy Science &Engineering, EarlyView.
CFD analysis of a diesel–CH4–H2 tri‐fuel engine shows that increasing hydrogen energy share (HES) enhances mixing and accelerates combustion, improving pressure, efficiency, and reducing CO and soot. At 60% HES, ISFC improves 26.2%, soot drops 95%, while NOx increases due to higher temperatures. ABSTRACT The global commitment to achieve net‐zero carbon
