Multiscale Coupling of Phase Transition and Urban Flow in Two‐Phase Chlorine Dispersion in Street Canyons

open access: yesSafety Science and Technology, EarlyView.
A multiscale CFD framework reveals that two‐phase effects fundamentally alter hazardous gas dispersion in urban street canyons. Droplet evaporation, vortex‐driven transport, and ventilation jointly control hazard evolution, with wind speed dominating dispersion while temperature plays a secondary role.

Prediction of Ceiling Temperature in Tunnel Fires Under Canyon‐Wind Conditions Using Ensemble Learning

open access: yesSafety Science and Technology, EarlyView.
A LightGBM‐based ensemble learning framework with SHAP interpretability analysis was developed for predicting ceiling temperature in canyon‐wind tunnel fires. The model demonstrated robust generalization (R2 = 0.7476) under unseen extreme conditions, with fire‐source location identified as the primary factor driving temperature evolution.

Influence of mix design method on the shear capacity of reinforced concrete beams made with high‐quality recycled coarse aggregate

open access: yesStructural Concrete, EarlyView.
Abstract This study investigates the shear capacity behavior of reinforced concrete (RC) beams without stirrups incorporating recycled coarse aggregate (RCA). An extensive database comprising 269 experimental data points from 40 journal articles published between 2001 and 2025 was compiled, excluding specimens with recycled fine aggregate or fiber ...

Modern Fire Safety Protocols in the Archeological Contexts: A New Tool for Studying the Health and Behavioral Effects of Fire Use in Semi‐Closed Spaces

open access: yesArchaeometry, EarlyView.
ABSTRACT This study evaluates the application of computational fluid dynamics (CFD) simulations, integrated with controlled fire experiments, to investigate combustion processes in semi‐closed spaces. The framework enables systematic modeling of smoke dispersal, particulate transport, and hearth performance under variable morphologies and ventilation ...
