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 …

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 …

In recent years, research activities about fire events in tunnel have received a significant
impulse, especially after several accidents. The Computational Fluid Dynamic (CFD) has a …

Fire behavior, especially its interaction with VENTILATION SYSTEM in tunnels, is still a
challenging issue for road tunnel designers. This paper presents the results of a study …

The issue of airflow dynamic in a road tunnel is considered in this study and its impact on
smoke management and people safety is highlighted. It was an attempt to estimate the time …

With the aim of evaluating capabilities of a tunnel ventilation system to control the spread of
smoke in the emergency operating mode, thereby providing conditions for safe evacuation …

ABSTRACT A mechanical ventilation system plays a major role in tunnels safety. Over the
world, different ventilation systems regarding to the tunnel geometry and other parameters …

The definition of the deterministic approach in safety analyses arises from the need to
understand the conditions that emerge during a fire accident in a road tunnel. The key factor …

The study presented in this paper concerns the ventilation system inside tunnels. The
ventilation system is responsible for the removal of exhaust gases produced by vehicles and …
