A modified critical velocity for road tunnel fire smoke management with dedicated smoke extraction configuration
Yunlong Liu - HNTB Corporation
(in lingua inglese)
Based on a typical example 2 lane road tunnel with a fixed smoke extraction rate of 282 m3 /s, Computational Fluid Dynamics (CFD) analysis has been performed on selected cases to investigate the modified critical velocity considering specific smoke extraction configurations and other parameters. These parameters examined included the extraction damper locations, total number of operating dampers, tunnel gradient, fire location and the traffic blockages in the tunnel region that is upstream of the fire.
