- Abstract
- In this study, numerical simulations were carried out to analyze the effect of the smoke extraction system and fire shutters in subway station fires using FDS 4.0. Subway station used in the experiment was 145 m long. Simulation results are validated by comparing with experimental results. Simulation results showed good agreement with experimental results within 10℃. 10 MW polystyrene was used as a fuel in the numerical prediction. Numerical predictions were performed in the center-platform type subway station in case of a kiosk fire. Temperature and CO concentration were lowered by the operation of smoke extraction system. But, the operation of fire shutters had little effect on temperature and CO concentration in the platform level.
