Fires in road tunnels produce a large amount of smoke threatening passengers lives and
health and tunnel facilities. The spread of fire smoke is influenced by various factors. In this …

Fires are among the most dangerous incidents in road tunnels that can cause large
damages to property and environment and threaten tunnel users. In this paper, the impact of …

More and more urban traffic tunnels are built due to the heavy traffic in dense urban areas.
Fire safety in tunnels is a concern due to the large traffic flow. Most of the urban tunnels have …

Three full scale tests were conducted in a road tunnel to study the smoke spread with
different fire sizes and wind speed conditions. The smoke temperature under the ceiling, the …

Based on the computational fluid dynamics (CFD) simulation model, the regularity of fire
spread and smoke movement occurred in typical tunnel is studied by numerical simulation …

To investigate the effect of tunnel slope on hot gas movement and smoke distribution in a
slopping tunnel fire, a series of tunnel fire models are built by fire dynamics simulator (FDS) …

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

In this work, a numerical model of tunnel fire is developed and aimed to investigate the
influence of cross-sectional fire locations on critical velocity and smoke flow characteristic. It …

With the development of transition, the mount of road and railway tunnels are more and
more in the world. But great loss due to the tunnel fires happened recent years shows that …

This paper concerns smoke propagation in tunnel fires with various size of fire source.
Experiments carried out in model tunnel and those results were compared with numerical …
