Experiments for Various Smoke Control Ventilation Modes in Platforms of Underground Subway Stations in Korea

초록

In this study smoke movement was visualized by using the smoke generator and heater for simulating the fire smoke in the platform of underground subway station for various smoke control ventilation modes. The station has been in operation since April 2004, in Gwangju, a medium-sized city in Korea. For smoke control during fires in a subway platform, smoke control zones are specified and designed to control smoke through smoke exhaust or air supply according to the fire’s location. Smoke control mode during fires in subway platforms is that the smoke zones operated by exhausting smoke while the other zones in the platform operated by supplying air or stopping any ventilation.
