摘要
利用流体力学计算软件建立火灾模型,对某大型机场航站楼进行自然排烟的数值模拟,根据火灾可能发生的烟气运动规律,计算模拟大空间内温度场和烟浓度场随时间变化的分布情况,得出了火灾到达危险时刻的时间。同时计算航站楼人员安全疏散所需的时间,将人员安全疏散所需的时间与火灾到达危险时刻的时间进行比较,得出航站楼购票大厅疏散设计能够满足安全疏散的要求。
A fire model based on CFD software was established and the natural smoke exhaust of a airport terminal was simulated. According to the law of smoke movement, the temperature field and smoke concentration field with the change of time were calculated and the danger time of fire was found. The time needed for personnel safety evacuation was calculated and compared with the danger time of fire. It is concluded that the evacuation design can satisfy the requirements of the safe evacuation.
