Smoke Control in Subway Tunnel Fires

Abstract

This paper concerns the smoke control modes and the critical ventilation velocity when the subway tunnel on fires. The standard for the smoke control mode is making sure the smoke exhausting in the shortest way. The critical ventilation velocity means it is just sufficient to prevent the smoke spreading upstream. The critical velocity in different heat release rates obtained though theoretical analysis and computer simulation. In the end, a simple formula to calculate the critical velocity can be fitting out.

An Explorative Methodology to Assess the Risk of Fire and Human Fatalities in a Subway Station Using Fire Dynamics Simulator (FDS)

“…The work modeled people's behaviors in learning routes in emergency evacuation situations. Zha and colleagues [24] used computer simulation and theoretical analysis to explore the subway station's critical ventilation velocity and smoke control mode. They built the model geometry using PyroSim software and performed analysis using FDS.…”
