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

Safety 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.

Flame lift-off and stabilization mechanisms of nonpremixed jet flames on a bluff-body burner

, 2010
[[abstract]]A detailed regime diagram for bluff-body stabilized flames is proposed for the flame lift-off and stabilization limits. At Low fuel velocities, the flame structure is classified into three stable modes: recirculation zone flames, jet ...

Investigation of the Evolution Mechanism and Multiphysics Coupling in Tree‐Contact Single‐Phase‐to‐Ground Fault

High Voltage, EarlyView.
ABSTRACT Tree‐contact single‐phase‐to‐ground fault (TSF) is a common and hazardous type of failure in distribution networks. TSF is likely to occur when overhead conductors contact moist tree branches, potentially leading to insulation breakdown, posing serious threats to grid safety.
