A fire growth and smoke movement model for a multi-compartment building has been developed at the National Research Council of Canada. This development is primarily intended to help evaluate the risk from fires in buildings. This paper presents the related physical models, numerical methods, and some verification examples. The 2-zone ordinary differential(More)

This paper presents the results of full-scale fire and environmental tests to study the use of video image detection (VID) systems for the protection of large industrial applications and atria. The tests were conducted in a large test atrium facility and a large burn hall. The effects of VID system variables, fire sources and environments on the performance(More)
This paper presents a study on the effectiveness of a smoke exhaust system in a complex building using the Computational Fluid Dynamics (CFD) models. The CFD model FDS (Fire Dynamics Simulator) was used for this study. To simulate fires in the building a design fire was selected to represent the fire loads expected in the lobby area. Smoke movement from the(More)
