Process Gas Transitions in the Steel Industry—Planning Corridors for Chemical Utilization

Chemie Ingenieur Technik, EarlyView.
Scenario‐based planning corridors link route‐ and pace‐dependent steelworks off‐gas availability (BFG, BOFG and SAFG) to a 1000 mtpd methanol demand over 2030–2060, revealing pace‐limited BFG concepts and route/site‐size limits for CO‐rich operation and motivating early CO2 tie‐ins as retrofit‐friendly safeguards.

Progress, Challenges, and Outlook for Sodium‐Ion Battery Recycling

CleanMat, EarlyView.
This review highlights the progress and challenges of sodium‐ion batteries (SIBs) recycling. It introduces the main material systems of SIBs and their degradation, outlines economic, technical, and environmental requirements, and evaluates four major strategies: pretreatment, pyrometallurgy, hydrometallurgy, and direct regeneration.

Numerical study of local scour effects on the lateral pile-soil interaction

, 2016
Local scour usually occurs around offshore pile foundations, which may bring the reduction of both the effective stresses in the surrounding soil and the effective pile embedment. Until now, the effects of local scour on the lateral pile-soil interaction

Acoustic‐driven surface cleaning with millimeter‐sized bubbles at translational resonance

Droplet, EarlyView.
Time‐lapse visualization comparing bubble trajectories. The top panel (0 Hz) shows a bubble's linear path under no acoustic forcing, while the bottom panel (50 Hz) demonstrates the oscillatory motion induced by acoustic waves at a resonance mode. This mechanism holds promising potential for applications such as surface cleaning.

Numerical Investigation of Local Scour Around Double Triangular Prisms Using a DBM–LBM Coupled Model

Journal of Marine Science and Engineering
Local scour is a typical hydro-sediment coupled process around near-bed obstacles. Its intensity and spatial distribution are jointly controlled by the surrounding-flow structure, sediment transport, and bed-feedback deformation.

Experimental and smoothed particle hydrodynamics‐finite element method simulation investigation of synergistic erosion mechanism of gangue‐based abrasive water jets

Deep Underground Science and Engineering, EarlyView.
This study proposes an eco‐friendly coal permeability enhancement technique by utilizing mine waste gangue as an abrasive in high‐pressure water jets. Integrating erosion experiments with smoothed particle hydrodynamics‐finite element method coupled simulations, the research study elucidates the flow field dynamics and a nonlinear solid–liquid ...

Effects of pile caps on local scour at bridge piers [PDF]

, 2006
The most existing pier-scour equations mainly apply to uniformly shaped piers. However, pier footings may often project above the streambed because of scour. This may be caused by either long-term bed degradation or local scour.

Influence of flow unsteadiness on local scour at bridge piers: An energy-based perspective

International Journal of Sediment Research
Local scour at piers is a major cause of bridge failures worldwide. While most existing studies assume steady flow conditions, actual flood events are inherently unsteady, with distinct rising and falling limbs that significantly modify scour dynamics ...

Temporal variation of clear-water scour at compound Abutments

Ain Shams Engineering Journal, 2016
Most of actual abutments in rivers are built on foundation, while there is limited number of study available on the effects of the foundation on the local scour.

Comparative study of local scour methods at bridge piers in the toribio river

, 2023
Local scour is a morphological process originated by the presence of a foreign object or an obstacle within water flow alignment; therefore, bridge piers act as the cause of this phenomena, generating a significant bed level change in a river´s cross ...
