Abstract

In the present study, a numerical simulation of the subway carriage fire is performed to determine the more effective operation of Trackway Exhaust System(TES) in underground stations. The four types of possible TES operation (OSUS, OSUE, OEUS and OEUE) is simulated and compared their removal capability of smoke and hot temperature for the carriage fire of 2MW. From the results, the distribution of temperature and smoke concentration is more dependent on the operation of fans located at upper side of the platform than those at lower side. It is also found from the results that for more efficient smoke control, the fans at upper side of the platform should be operated as an exhaust system. Whereas the fans at lower side can be operated as a supply system to aid upper exhaust fans.
