摘　　要：通过对大型舱室水幕分隔在不同水幕厚度、喷水速度、水珠直径和水幕流量下火灾烟气流动及传热过程进行系列模拟计算,得到了大型舱室起火后和火灾过程中,空间温度、烟气流动随时间和空间的变化规律。分析了影响水幕对火焰及烟气阻碍作用的主要因素,以及水幕分隔的防火效果,并对仿真计算结果与试验结果进行了对比分析。From a series of simulation analysis on fireproof water curtain with different thickness, spouting velocity, bead dimension and flux of water, this paper introduces the temporal and spatial changing regularity of emperature and smoke flow in a cabin with long-span and hyper-surface after ignition and within fire. The main factor for block effect on flame and smoke spreading by water curtain is analyzed. The results of simulation analysis and test have been compared.
