摘要: 采用 FDS 模拟与理论计算相结合的方法,设定 6 种上、下开口面积之比的工况进行模拟,研究自然排烟口对机场航站楼排烟效果的影响。结果表明:当上、下开口面积之比不大于 1.8时,随着排烟口面积增加,室内平均温度下降,烟气层高度抬升,排烟效果越来越好;当火灾发展至 720 s 时,室内平均温度仍在安全范围内,对于人员疏散影响不大。建立理论模型,与模拟结果进行对比,得出当上、下开口面积之比为 1.8 时理论模型适用性较好。

Abstract: The method of combining FDS simulation with theoretical calculation was used to study the influence of natural smoke outlet on the smoke exhaust effect of airport terminal based on 6 scenarios with different ratio of upper and lower opening area. The results showed that when the ratio of upper and lower open area is not greater than 1.8, with the increase of smoke outlet area, the indoor average temperature drops, and the height of smoke layer rises, the smoke exhaust effect becomes better and better. When the fire develops to 720 s, the average indoor temperature is still within the safe range, which has little impact on the evacuation of personnel. The theoretical model was established and compared with the simulation results. It is concluded that the theoretical model is applicable when the ratio of upper and lower opening area is 1.8.

Key words: natural exhaust smoke, smoke extraction effect, personnel evacuation, simulation analysis, theoretical calculation
