腔室火灾烟气向远距离房间的传播迁移

Transport of smoke from the compartment fires to the remote target room

利用数值模拟方法研究了腔室火灾产生的烟气通过毗邻的走廊向远距离目标房间传播迁移的规律。结果表明,烟气到达走廊弯处远距离目标房间的时间接近或少于到达某些中间位置房间的时间,有些远距离目标房间中烟气的下降时间反而短。这就解释了遇难者大量死于远距离处的主要原因。

Numerical simulation approach is applied to study the characteristics of transport of smoke from the compartment fires in the target room through the adjacent corridor. It is determined that it takes less time for the smoke transporting to remote places than to near room, while the smoke reaching remote target rooms descend to the floor more quickly than that near the fire origins does, which make it clear that many fatalities occur remote to the fire origins.
