AbstractA research project has been conducted at the National Research Council of Canada (NRC) to evaluate the effectiveness of in-place emergency ventilation strategies to control smoke spread in the event of a fire in a road tunnel. Some of these strategies date back to the design of the tunnel (1964). Following a recent fire, the operating instructions were revised. A scientific based evaluation of these operation instructions is the main objective of the research study. The research includes both numerical and experimental studies. The numerical study uses the Computational Fluid Dynamics (CFD) model Fire Dynamic Simulator (FDS) to investigate smoke ventilation in tunnels. The experimental study is used to provide the necessary initial and boundary conditions for the CFD model.
