| 中文摘要: |
| 喷出火焰和旋转火焰是室内火灾火焰的两种常见存在形式。利用小规模室内火灾试验装置和FDS软件,对室内火灾喷出火焰和旋转火焰进行了实验模拟和数值模拟;根据模拟结果,提出了小规模室内火灾条件下喷出火焰根部温度估算公式,分析了室内火灾火焰旋转的机理及其引起热烟气层温度、地板辐射热通量等参数升高的原因。 |
| 英文摘要: |
| Extrusive flames and whirling ones are two common presences of flame of enclosure fires. The two kinds of flames in
enclosure fires are experimentally and numerically simulated separately in a small- scale enclosure fire test device and by FDS
software. According to simulated results, the equation of estimating root temperatures of extrusive flames of small- scale enclosure
fires is put forward, and the mechanism of whir ling flames and causes for increase of some parameters such as hot gas
layer temperatures and floor radiant heat flux are analysed. |
