Railway Station Pedestrian Simulation on Fire Smoke Based on Smartfire

Fire on railway station is a very important disaster is worth of consideration. When fired, smoke will bring many pollution gases and harmful particles with high temperature. Study the smoke flow phenomenon will provide help for people´s lives. In the article, the author use the Smartfire software to simulate the fire on the station, it has provide the critical ventilation velocity that will disturb the fire smoke to flow back and can help people to escape when there is fire also. The result is that when ventilation velocity is 2.5m/s can help people to escape effectively and pollution gases distribution can give management help for people escape.
