Simulation and Experimental Investigation of Smoke Extraction in Metro with Safety Door under Fire Conditions

Zhao Zhenjiang;Zhu Peigen;Chen Lei;Cheng Lijie;Nanjing Metro Operation Co.Ltd;PLA University of Science and Technology;  
In recent years,in many cities there are already security doors installed in metro station,the security door system will affect the distribution of the flow of smoke and temperature in station when there is fire on train at the station.In this paper,the equivalent resistance coefficient of the security door has been worked out by the coupling of the field simulation and network simulation.The volume of air entering is worked out by the simulation with STESS under that equivalent resistance coefficient,they will be used as boundary condition substituted into the FDS field simulation.The air temperature in the station,the speed of wind and visibility of the station is worked out by the simulation of FDS in simulation ventilation and smoke exhaustion conditions.Combined with the measurement and analysis of the actual wind speed data,the smoke exhaustion evacuation mode,which is conducive for evacuation,is worked out.
