摘要
运用FDS火灾模拟软件对不同风速和风向(共9种工况)条件下的某竖井型自然通风隧道火灾进行了数值模拟,并对模拟结果进行了对比和分析,得到隧道风速和风向对隧道火灾时纵向速度场的影响规律。
This paper adopts FDS which is a software to conduct a numerical simulation when a fire happens in the natural ventilation city tunnel with vertical shafts.The paper has got the variation of the velocity field of the fire smoke and then analyzed the result that the wind velocity and direction has the impactions on the horizontal velocity field
