AbstractA research project has been conducted at the National Research Council of Canada to evaluate the effectiveness in a road tunnel of the current emergency ventilation system to control smoke spread in the event of a fire. The research includes both numerical and experimental studies. The numerical study uses the Fire Dynamic Simulator model to investigate smoke ventilation in tunnels. The experimental study is used to validate the numerical model and to provide the necessary initial and boundary conditions.This paper investigates the effect of the meteorological parameters and tunnel slope on the performance of in-place emergency ventilation strategies in a section of a road tunnel. The study recommends methods for improving the performance of the ventilation strategies in order to promote a safer environment in the tunnel section.
