Numerical modelling of smoke stratification in underground car parks

Fire accidents in underground car parks have a significant impact on the building structure and lives of humans and firemen. Different methods are used to obtain a reliable estimation of fire and hot smoke influence on the building structure. Numerical modelling is crucial in the fire design and is a useful tool to determine smoke stratification and clear layers for safe human evacuation and firemen approach. Smoke stratification can be checked separately for any time interval in any section of an underground car park, regardless of the underground car park architecture complexity. This paper describes numerical modelling of smoke stratification and movement in an underground car park. The results show smoke movement and smoke layer thickness during the evacuation time, and they can help reduce the harmful influence of fire on the underground car park structure.
