| 中文摘要: |
| 以高层建筑为研究对象,应用FDS软件对高层建筑火灾燃烧规律进行数值模拟计算。比较分析了不同燃烧时刻的烟气、温度和CO2浓度等变化特征,得到了高层建筑火灾时的烟气运动、着火点附近区域温度变化、CO2浓度变化等计算结果。本文数值模拟计算为高层建筑性能化防火设计及人员紧急疏散提供一定的理论依据。 |
| 英文摘要: |
| Taking high-rise building as an example, in this paper, the combustion characteristics of high-rise building fire is simulated by FDS software. By comparing the variation characteristics of smoke ,temperature and co2 concentration in the different burning time, the calculation results of smoke movement, temperature varieties and co2 concentration varieties and so on are obtained when the high-rise building burning. The numerical simulation calculation provides the theory basis for performance-based fire design and emergency evacuation of high-rise building. |
