Effect of the Open Ways of Screen Doors on Fire Smoke in a Subway Platform

AbstractUnder certain conditions, the screen doors of the platform can affect smoke spread and evacuation in a subway fire. The physical model and mathematical model were established by taking a real subway station as an example. And the smoke spread in a train fire was simulated by using CFD method. Effect of four open ways of screen doors on fire smoke and evacuation were analyzed. The research can provide a theoretical basis and technical support for the emergency evacuation plan and performance-based design of the subway
