This study analyzes the physics characteristics of the flame plume temperature, induced by a
ceiling jet and their coupling with an extraction flow. As it is knows, the maximum increase in …

In order to reduce risk and increase resilience of transportation tunnels, the early-phase
detection and protection of fire are of great significance for the safety assessment of tunnel …

Tunnel fire is one of the most severe global fire hazards and causes a significant amount of
economic losses and casualties every year. Over the last 50 years, numerous full-scale and …

Sealing the tunnel entrance is one of tactic for railway tunnel firefighting. In order to
understand the effect of tunnel entrance sealing ratio on fire behavior, Computational Fluid …

Long-large subway tunnel accommodates the requirements of high-speed operation of
trains, but also poses challenges on smoke control in case of tunnel fire. In conjunction with …

In order to research the fire characteristic of hydrogen jet fire in tunnels under different
conditions, computational fluid dynamics (CFD) simulations of the hydrogen jet fire from a …

A series of experiments were carried out in a model-scale tunnel [72 m (length)× 1.5 m
(width)× 1.3 m (height)] to investigate the buoyant flow stratification behaviors in a tunnel fire …

To advance understanding of the ceiling temperature characters in tunnel fires, a physical
model-free ant colony optimization network algorithm is developed. Compared to the …

Railroad transportation has been widely adopted and developed in recent years. In
particular, many railroads have been built on complex terrains such as plateaus and …

Under the influences of the chimney effect and longitudinal ventilation, the risks of
continuous spill fires in inclined tunnels are catastrophic with great complexity and …
