Abstract

In this study, fire simulations were performed to analyze the characteristics of the fire driven flow and the effects of the platform screen door on the smoke flow in the station, when the fire occurred in the center of the platform. Soongsil Univ. station (line number 7) was chosen which is the one of the deepest (47m) underground subway stations in the Seoul metro(SMRT). The parallel computational method was employed to compute the heat and mass transfer eqn's with 6 CPUs of the Linux clustering machine. The fire driven flow was simulated using FDS code in which LES method was applied. The heat release rate (HRR) was 10MW and The ultrafast model was applied for the growing model of the fire source. The 10,000,000 structured grids were used.
