地铁火灾模拟研究

Simulation of Underground Fire

简述了地铁火灾的特点、危害性及烟气控制方法,介绍了主要的火灾模型及数学模型,以及CFD软件Flu-ent的处理过程,并对假设隧道进行模拟,提出了进行地铁火灾温度场、速度场及烟气流动的数值模拟。

This paper briefly introduced the characteristics and hazards of underground fire and reviewed the researches on smoke control of underground fire. It also introduced the main fire models, numerical models and the handling process of CFD software Fluent, and simulated the tentative tunnel so as to put forward the numerical model to simulate the temperature, velocity and smoke of underground fire.
