腾龙公寓火灾模拟研究

Fire Simulation of Tenglong Students' Dormitory

为了对高校学生公寓进行火灾风险研究,运用FDS软件中的大涡模型模拟某高校腾龙公寓发生火灾后的烟气运动特征和区域温度变化情况。模拟结果表明,火灾初期烟气快速聚集,温度缓慢上升,是扑灭火灾的最佳时期;当火灾进入明火燃烧阶段时,火势将全面爆发,室内温度高达几百摄氏度,火灾难以扑灭。安装喷淋系统和排烟系统后,火势将得到明显控制。

Characteristics of smoke movement and regional temperature changes were simulated after a fire happening in Tenglong Students'dormitory by the large eddy simulation method of FDS to research the fire risk in university students'dormitory.Simulation results showed that smoke gathered quickly and temperatures went up slowly at the beginning of a fire ,which can be the best time to put out the fire .But when open fire appeared and the temperature in the room went up to hundreds of degrees ,it is very difficult to put out the fire.The fire can be controlled if the spraying system and the smoke evacuation system have been equipped .
