Using a CFD simulation in designing a smoke management system in a building

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 origin of fire in the lobby and smoke contamination in the interconnected corridors are simulated in order to design the exhaust system to be capable of maintaining tenable conditions in the corridor used for evacuation. The results of these simulations are presented and discussed.
