Abstract
Compartment fire is an unwanted event that needs to be accessed carefully in order to ensure the safety of occupants and structures. This study emphasizes on fire and smoke spreads in a typical underground
metro station. Underground metro station usually has a geometry that will direct smoke in the same
direction as the evacuation course. Thus, to secure safety of the passengers, the rate of the smoke spread and stratification should be reduces by well designed
smoke ventilation systems. This paper examines the performance of ventilation configurations proposed
for a typical underground metro station design. The study was carried out by using numerical model of
Fire Dynamics Simulator version 6.0 and fire test in 1:25 bench scale of a typical metro underground
station. Three ventilation configurations will be provided in this paper namely, mechanical ventilation, natural ventilation, and hybrid
ventilation. The objective of this study is to formulate ventilation strategies in order to optimize the smoke
handling capacity for lengthening the available safe egress time (ASET) during a fire event in a typical
underground metro station. The discussion will also include the effect of hybrid ventilation on the
occurrence of the pulsating phenomenon of smoke flow.
