dc.description.abstract | In fires of subway stations, the most immediate threat to passengers’ life is not the
direct exposure to fire, but the smoke inhalation because it contains hot air and toxic gases. To
understand the mechanisms driving the motion of smoke is therefore an important issue of fire
safety, and the stack effect is found to be an important mechanism having significant influence.
In this paper, we compute the three-dimensional smoke flow fields under various fires happened
in a representative subway station of Taipei Rapid Transit System. To clarify the mechanisms
corresponding to the stack effect, a simplified three-dimensional configuration is also considered.
Results indicate that, without mechanical smoke control, the stack effect plays a decisive role and
is virtually the sole factor influencing the smoke movement. Because of the stack effect, most or
sometimes all of the smoke will choose a vertical shaft (usually a stairwell) to evacuate, and the
cross sectional area of the shaft and the location of fire determine which shaft is chosen. Present
computational results show the evidences of the importance of the stack effect and provide both
valuable information to the design of the passenger evacuation routes in fires as well as criteria
to the design of smoke control systems of subway stations. | en |
