| 摘 要： | 本文利用CFD软件对机场候机楼自然排烟下的烟气流动进行模拟研究。将模拟结果结合疏散时间分析后得到,候机楼大空间的蓄烟作用和屋顶安装的自然排烟窗能保证烟气在疏散时间内保持足够高度,且短时间内不会下降到危险高度,不需要另行安装大功率排烟设备,可减少防火投资,增加商业建筑的经济效益。本文也同时为人员疏散方案提供了理论基础。

| Abstract: | CFD software is used to simulate smoke movements in natural ventilation working condition of the terminal building in this paper.The simulation result which combined with the evacuation time indicates that the smoke storage effect of the large space and the natural smoke window that installed on the roof play a important role to maintain the smoke enough height during the evacuation time and could not fall to a dangerous height in a short time.Do not need to install high-power exhaust equipment,and so this ... |
