| 摘 要： | 通过建立高层住宅凹口内烟气流动的数学模型，分析研究凹口内烟气对外廊的影响，得出在火灾发生初期，烟气主要影响靠近火灾发生层以上几层的外廊，随着时间的推移，烟气影响区域逐渐向上移动，在烟气发生量稳定后烟气主要影响距火灾发生层十层以上的外廊。不同的凹口尺寸，烟气会对外廊有不同的影响，横向增大凹口尺寸并不会对外廊烟气分布产生显著的影响，纵向增加凹口尺寸，能降低烟气对外廊的影响。

| Abstract: | By establishing the mathematical model of smoke gas flow in concave opening of high-rise housing, this article analyzes the impact of smoke gas in concave opening on verandahs, and reaches conclusions that smoke gas mainly affects the verandahs of several storeys above the storey with outbreak of fire at the early stage of fire, the area affected by smoke gas moves upwards gradually with the passage of time, and smoke gas mainly affects the verandahs of storeys above more than ten storeys above the storey w... |
