Abstract
A research study was conducted at the National Research Council of Canada to evaluate the effect of different parameters on the performance of the emergency ventilation system in the event of a fire in a newly-constructed section of a road tunnel. The parameters included: tunnel cross-section width and height, tunnel slope, fire size and location, meteorological conditions, and mode of fans operation. This study aimed at assessing the ability of in-place emergency ventilation strategies to control smoke spread and minimize its impact on tunnel users using both numerical and experimental approaches.In total, four field fire experiments and seven numerical simulations were conducted. The field measurements included the measurements of temperature, airflow speed and smoke optical density. Based on the study, recommendations were made to optimize the ventilation strategies in the tunnel section. This article presents the details of the study as well as the recommendations made.
