This chapter describes the general basis of Computational Fluid Dynamics (CFD) codes,
outlines the models used in smoke movement analysis, and the paper attempts to describe …

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 aim of this study was to design a fire ventilation system with impulse jet fans for an
underground car park. With respect to the number of parameters affecting the spread of …

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 aim of this study is to provide a novel correlation to evaluate the pressure loss, in road
tunnel, for different traffic jam conditions (Filling Tunnel Traffic, FTT). The proposed …

In the past, ventilation systems were mainly designed on the basis of the fresh air required
for maintaining an acceptable air quality in the tunnel, notably sufficiently low concentrations …

In the framework of the Research Project CTM2005-00187/TECNO,\“Prediction models and
prevention systems in the particle atmospheric contamination in an industrial environment” …

The determination of the aerodynamic coefficients of highway tunnels is crucial to set up an
accurate theoretical model of tunnel ventilation. Their appropriate values vary with …

Abstract Advances in CFD (Computational Fluid Dynamics) and significant increase of
computational power of current computers have led to widespread use of CFD in …

Providing efficient ventilation in road tunnels is essential to prevent severe air pollution
exposure for both drivers and pedestrians in such enclosed spaces with heavy vehicle …
