| 摘 要： | 飞火是城市火灾特别是城市震后火灾的重要蔓延方式之一，它可以使火灾在相距较远的离散可燃物之间进行跳跃式蔓延，从而增加了扑救难度，威胁扑救人员的安全。因此，对飞火蔓延现象的认识和飞火蔓延距离的计算是降低飞火危险性的前提。基于Baum-McCaffrey火焰羽流模型，重点研究在城市火灾羽流中球形飞火颗粒的上升行为和环境风影响...

| Abstract: | Spotting is one of important propagation mechanisms for large-scale urban fires,especially for post-earthquake urban fires.Firebrands can start new ignitions beyond the continuous fire zone and lead to fire spreading in a non-continuous way,so it can impend fire controlling and threaten to firefighters' safety.Understanding the propagation distance of firebrands is the premise for reducing the risk of spotting fire.Based on research results of Baum-McCaffrey fire plume structure,this work is an effort to st... |
