Tunnel fire testing and modeling : the Morgex North Tunnel experiment

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 act...
