CFD-approach in investigation of consequences of accidental large-scale fires

Dr. Medzid Muhasilovic - EPFL Swiss Federal Institute of Technology AbstractDue to the increasing accidental fires in enclosures, especially in that area of modern society where our freedom is mostly expressed – traffic and tourism – there is an on-growing need to undertake scientific and technological research, aiming at better understanding of these reactive flow phenomena and their consequences. One of the direct benefits coming out of such research is implication of optimal methods for fire suppression that certainly must get along with world-wide statistical data for one tunnel-fire on each 107th kilometre of covered (tunnel) road.
Results of the CFD-investigation on simulated heptane-fires of Heat Release Rate (HRR) of 20MW and of 50MW within two different road tunnels without forced longitudinal ventilation, are presented, pointing at both at the direct and indirect consequences of such large-scale uncontrolled combustion.Keywords: Fires in Enclosures, HRR, Tunnel, Soot Distribution, Irradiance
