This paper investigates the flame extension length and temperature profile in a thermal
impinging flow, induced by a buoyant turbulent round jet impingement upon a horizontal …

In this work, experimental analysis and machine learning modeling of maximum ceiling
temperature for wall fire in longitudinally ventilation tunnels were conducted. The results …

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 …

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 …

This paper investigates experimentally the thermal buoyant smoke back-layering flow length
beneath the tunnel ceiling with combination ceiling extraction and longitudinal ventilation …

This paper systematically studies the effect of ambient pressure on smoke movement in
tunnel fires by numerical investigations. Because of the correlation between ambient …

The effect of bifurcation structure in a road branched tunnel on ceiling gas temperature
needs to be clarified. However, the previous studies mainly focused on the temperature …

Experiments are conducted in a model tunnel to study the effect of a vehicular blockage at
the upstream of the fire source on the buoyancy driven back-layering length and critical …

Experiments based on Froude scaling law were conducted in a 1/10 reduced-scale model
tunnel to investigate the effect of slope on critical velocity in tunnel with longitudinal …
