Tunnel Wind is occurred by various causes of gradients of railway, locally different temperature and car moving in the subway. In this study, transient numerical-simulations were performed to analyze the effects of the platform screen door and tunnel wind on the fire driven smoke and heat flow in the station, when the fire occurred in the center of the platform. Soongsil Univ. station (line number 7, 47m in depth underground) was chosen which was the one of the deepest underground subway stations in the Seoul metros. The 16 cores of linux clustering-computer were employed for fast calculation of 10,000,000 structured-grids. The fire driven flow was simulated with FDS code in which LES method was applied. The Heat release rate was 10MW and The Ultrafast model was applied for the growing model of the fire source.
