室内火灾轰燃喷出火焰的数值模拟研究

利用FDS软件等对小规模轰燃后火灾的喷出火焰进行了数值模拟,得到了喷出火焰的根部温度、平均温度、辐射热通量等重要参数的模拟结果;将这些模拟结果与同等条件下的实验结果进行了对比分析,发现二者之间比较吻合。研究表明：利用FDS等模拟喷出火焰的可靠性较高,根据模拟结果可以进一步研究喷出火焰的有关问题。

A Digital Simulation Study on Extrusive Flames in Post-flashover Fires

Extrusive flames in small-scale post-flashover fires were numerically simulated by FDS software,and the results of some important parameters of extrusive flames such as root temperatures,or temperatures and radiant heat flux were gained;these results were compared with tested ones in experiments under the same conditions,and it is found that they agree well with each other.The study shows that the simulated results of extrusive flames by FDS etc are quite reliable,and the relevant problems of extrusive flames can be further researched basing on simulated results.
