Study On CFD Subway Fire Numerical Simulation Based Evacuation And Rescue

Urban rail transit is important part of modern systematic transport systemand it has high speed and great carrying capacity. Although urban rail transitian independent and closed system, and the order is controllable, the whole complex system and high technology of operation may bring on serious result when some fire accidents happened. Then, it is necessary to analyze and study the fire acciden and the evacuation in urban rail stations.This paper aimed at urban subway station,which is the planing of the 2th line about zhangjiapu rail station in xi'an. study on several critical problem which associated with subway station fire accident. Based on the mathematical model of aerodynamics and the subway system combustion basic theory, use the CFD numerical simulation law, Analysis the temperature and gas field distribution of Fire subway system. Find the fire spreading laws ,Quantitative analysis of fire Subway to reach a dangerous state of the time. And acroding to the Architectural forms and topographical features of the station, use the Professional simulation modeling software calculated the system within the safe evacuation of time.and the evaluate the subway station fire safety performance. The issue of numerical simulation subway fire safety and evacuation of research, this Issues has very important significance to control fires ,reduce fire losses, support personnel safety, and ensure the safe operation and so on.
