| Abstract | A research study was conducted at the National Research Council of Canada to evaluate the effect of different parameters on the performance of emergency ventilation systems in the event of a fire in a section of a road tunnel. The parameters included: tunnel cross-section width and height, tunnel slope, fire size and location, meteorological conditions, and modes of fan operation. The 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. Four field fire experiments and eight numerical simulations were conducted. Based on the study results, recommendations were made to optimize the ventilation strategies in the tunnel section. This article describes the conducted in-situ fire tests and presents test measurements used to provide the initial and boundary conditions for the numerical simulations. |
