EFFECTS OF VENTILATION FLOW SPEED IN RECTANGULAR TUNNEL ON FIRE SIZE OF SUBWAY CAR

초록

Fire sizes (heat release rate) of a subway car in a rectangular tunnel with various tun nel ventilation flow speed are investigated using numerical simulations. Pyrolysis of the interior mate rials of the subway car is considered for fire propagation. The properties of the subway car interior materials were obtained from bench scale tests and literature. All side doors are considered open for analysis to account for passengers opening the doors to escape from the subway car when a fire o ccurs.
