| 摘 要： | 分析了烟气在中庭式建筑内的充填特点，并在中国科学技术大学和香港理工大学合建的大空间火灾实验厅内进行了对比试验．实验和计算结果表明，中庭内，烟气的充填过程很快，在烟气层形成的开始阶段的下降速度约为０．２ ｍ／ｓ，８ ｍｉｎ 左右接近地面．用区域模型计算烟气的充填过程仍具有足够的精度．

| Abstract: | Smoke filling characteristics are discussed using the zone model, and some experiments were conducted in the Large Space Fire Experimental Hall co constructed between USTC and PolyU, HK. The comparison between experimental results and numerical calculation shows that the development of smoke layers in atria can still be calculated with the zone model. The velocity of smoke filling in a 27m high atriium is about 0.2 m/s at the beginning stage of fire; and the smoke will fill of the whole atrium in about 8 minutes. |
