AbstractIn 2006, Phase 2 of the International Road Tunnel Fire Detection Research Project was initiated. As part of this project, a series of fire tests were conducted in a laboratory tunnel facility to evaluate the performance of detection systems under limited airflow conditions and longitudinal airflow conditions. In addition, fire tests were also conducted in the Viger tunnel in Montreal. In conjunction with the full-scale experiments, CFD simulations were conducted. The numerical predictions were initially validated against data from a demonstration test and subsequently using the results of selected laboratory and field experiments. Simulations were conducted to investigate the impact of various parameters including fire scenarios, ventilation mode, and tunnel length on fire behaviour and detection system performance. The results of the full-scale experiments conducted in the Viger tunnel roadway tunnel and the results of the numerical simulations are discussed in this paper.
