Multi-cell concept for simulating fires in big enclosures using a zone model

The multi-cell concept is applied to simulate fire in a big compartment with the zone model CFAST. The predicted physical properties of the smoke layer are used to justify the results, including the smoke layer temperature, smoke layer thickness and flows between each cell. Microscopic pictures of the flow pattern and smoke temperature distribution similar to the results pre-dicted by the Computational Fluid Dynamics technique can be obtained. This idea is recommended to study fires in big enclosures.
