Road tunnels are equipped with various safety installations that enable the tunnel's
autonomous response to fire in order to ensure conditions suitable for safe self-rescue and …

To investigate the performance of current emergency ventilation strategies for an existing
road tunnel system in the event of a fire, a research project is being conducted by the …

The efficiency of tunnels systems is often evaluated using numerical simulations. This
concerns both to normal and emergency mode of tunnel systems operation. Therefore the …

Many regulatory authorities are now requiring that the emergency ventilation system in a
road tunnel be validated using computational fluid dynamics (CFD). Several such codes are …

The objective of the Mechanical Ventilation Systems (MVS) in highway tunnels [1] is to
provide tunnel patrons with a reasonable degree of comfort during normal operation and to …

Ventilation and fire safety design in road tunnels are one of the most complex issues that
need to be carefully considered and analysed in the designing stage of any potential …

In this paper the FDS 6 code ability to simulate the airflows generated by jet fans in a real
road tunnel is studied. A transient model of the 898 m long bi-directional highway Polana …

A study has been conducted at the National Research Council of Canada to evaluate the
effectiveness of in-place emergency ventilation strategies to control smoke spread in the …

The effect of the vehicular blockage in a tunnel under longitudinal ventilation smoke control
was systematically studied using a small-scale tunnel (1: 30 of a standard tunnel section) …

The present works investigates with numerical methods the performance of longitudinal
ventilation system and the structural response of a tunnel in case of fire. Computational fluid …
