| 摘 要： | 轰燃是火灾由局部向全面转变的一类特殊火灾现象,危害极大,很多因素会影响轰燃,其中火源对轰燃的发生有重要影响。本文利用场模拟软件FDS5进行了火源释热率及其燃烧时间对标准房间轰燃的影响研究,结果表明:火源释热率必须超过某个临界值才能发生轰燃;发生轰燃的时间和临界火源供热时间与火源释热率间均符合乘幂函数关系;火源只需在轰燃前供热一段时间就足以引发轰燃。

| Abstract: | Flashover,often resulting in fatal disaster,is a special transition phenomenon after which fire spreads from the area of localized burning to all combustible surfaces within the room.The occurrence of flashover depends on many parameters.Among these factors,fire source plays an important role.This paper studies the effect of its heat release rate(hrr) and burning time on flashover in standard room using the fire field model Fire Dynamics Simulator(FDS5).The results show that the occurrence of flashover requ... |
