基于FDS的室内火灾回燃现象数值模拟分析

Based on the FDS indoor fire back-burning phenomenon numerical simulation analysis

用FDS对一次火灾现场进行数值模拟,通过分别设置不同火源功率、不同火源位置,以及加入不同位置排烟送风进行对比分析,探究室内火灾回燃现象中的一些通性,结合消防员灭火救援过程中的常见行为,得出安全建议。

Using FDS to a fire scene numerical simulation,by setting different fire power,different fire position and adding different smoke exhaust and air supply in different positions,this paper makes a comparative analysis to explore some commonalities in the phenomenon of backfiring in indoor fires,combined with the common behaviors of firefighters in the process of fire fighting and rescue,safety suggestions are made.
