In the past two decades, the interest in fire safety science of tunnels has significantly
increased, mainly due to the rapidly increasing number of tunnels built and the catastrophic …

Most of the underground buildings rely on mechanical ventilation system for achieving an
acceptable indoor thermal comfort level. In order to alleviate the greenhouse effect, it is …

In order to investigate the effect of strong environmental wind on a tunnel fire under natural
ventilation, a series of numerical simulations were conducted using large eddy simulation …

Numerical simulations were carried out to study the smoke behaviors induced by fires in
inclined tunnels with different slopes and the upstream maximum temperatures along the …

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 …

A series of simulations are conducted in a full scale road tunnel to explore the effect of
ambient pressure on smoke movement and temperature distribution in tunnel fires. Once a …

Thermal-driven smoke flow is the greatest threat to the trapped people in tunnels, and the
basic understanding of the smoke transport characteristics is necessary for the engineering …

When a fire occurs in an inclined tunnel, the tunnel inlet air velocity induced by the stack
effect will help to prevent the smoke backflow. This work presents numerical studies on the …

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 understanding of natural ventilation in super-long tunnels can help to optimize the
design of ventilation systems and reduce energy consumption and maintenance costs. This …
