ASPECTS OF FIRE SMOKE MOUVEMENT IN SUBWAY STATION
The development of computer applications in the field of fluid dynamics has led to increased numerical fire simulations in underground stations, tunnels or underground structures. From a constructive point of view, the subway stations are characterized by large openings, by which they enter sufficient amounts of air, which can, in the case of a fire, either to feed with oxygen combustion or to contribute to the evacuation of smoke. When a fire is held in a subway station, the amount of smoke emitted usually floods the subway station or the tunnel (depending on the place of the fire outbreak), including the evacuation routes of passengers. This leads to reduced visibility and can cause deaths from smoke intoxication. Thus, one of the main concerns is the protection of the escape stairs from the danger represented by the smoke emitted from the fire. On the other hand, it is essential that firefighters reach as close as possible to the fire outbreak and extinguish it.
