摘要

以广州地铁3号线沥滘地铁站为例

通过火灾动力学数值模拟软件FDS (Fire Dynamics Simulator)研究了多火源情况下

空气幕厚度、空气射流速度及角度对火灾烟气阻挡效果的影响. 通过对比数值模拟得到的烟气蔓延、温度变化与能见度变化情况

得到了楼梯口处设置挡烟空气幕时的特征参数适宜范围.

Abstract

Taking the Lijiao Metro Station in Line 3 of Guangzhou Metro as an example

the smoke control efficiency of the air curtain with different characteristic parameters (thickness

jet velocity and jet angle) is studied by FDS. The distinctions of smoke spread

temperature profile and visibility between different simulated scenarios are observed by comparing the numerical simulation results. The suitable range of parameters of the air curtain for the metro is determined.
