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 …

To investigate traffic tunnel ventilation flows, a scaled model of a traffic tunnel with
longitudinal ventilation system based on ducted fans is used. Flows in tunnels are …

The accurate computational modelling of airflows in transport tunnels is needed for
regulations compliance, pollution and fire safety studies but remains a challenge for long …

Numerical methods are applied to simulate the smoke behavior in a ventilated tunnel using
large eddy simulation (LES) which is incorporated in FDS (Fire Dynamics Simulator) with …

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 …

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 …

In this paper a preliminary tridimensional CFD analysis is carried out for a future realization
of a reduced-scale road tunnel experimental apparatus of 1/50 equipped with different …

A flexible and versatile full-scale CFD modeling strategy of the airflow in a road tunnel is
described. As applied to the case of the Mont-Blanc tunnel, the model includes the entire …

This paper applies a novel and fast modelling approach to simulate tunnel ventilation flows
during fires. The complexity and high cost of full CFD models and the inaccuracies of …

The final results of an SERC/DTI-funded LINK scheme to investigate the aerodynamic
characteristics of road tunnels ventilated longitudinally by jet fans are presented. The paper …
