This book aims to cast light on all aspects of tunnel fires, based on
experimental activities and theoretical and computational fluid dynamics
(CFD) analyses. In particular, the authors describe a transient
full-scale fire test ( 15 MW), explaining how they designed and
performed the experimental activity inside the Morgex North tunnel in
Italy. The entire organization of the experiment is described, from
preliminary evaluations to the solutions found for management of
operational difficulties and safety issues. This fire test allowed the
collection of different measurements (temperature, air velocity, smoke
composition, pollutant species) useful for validating and improving CFD
codes and for testing the real behavior of the tunnel and its safety
systems during a diesel oil fire with a significant heat release rate.
Finally, the fire dynamics are compared with empirical correlations, CFD
simulations, and literature measurements obtained in other similar
tunnel fire tests. This book will be of interest to all engineers and
public officials who are concerned with the nature, prevention, and
management of tunnel fires.
