摘要

采用湍流数值模拟的方法

对火灾情况下

北京地铁一、二号线中的典型单层岛式车站公共区加装挡烟垂壁前后的多个工况进行了数值模拟

数值模拟几乎完全根据现有实际物理边界

而且考虑了列车和灯光发热、人员发热以及人员对流动的影响。通过数值模拟

得到了设置挡烟垂壁前后车站温度场和烟气的流动情况。结果表明

北京地铁一、二号线老式岛式车站设置挡烟垂壁后

能够抑制烟气流动和降低站台疏散通道温度

大大提高车站火灾时的安全性。

Abstract

Using turbulent flow numerical simulation

a number of conditions before and after smoke screen installation in the typical single-island station’s public area of Beijing subway were simulated in the fire situation.The numerical simulation work is entirely based on existing actual physical boundaries

and considers the heating from the train and lighting

also from the people and the personnel effects on flow. The temperature and smoke flow situation before and after setting up the smoke screen were analyzed by numerical simulation.The results show that setting up the smoke screen for old island station of Beijing subway is important.It can inhibit the smoke flow and reduce the temperature of evacuation channel.It will greatly improve the safety of the station under fire.
