为了解多层教学楼建筑火灾的蔓延和烟气运动，针对火灾烟气的蔓延特性，利用计算流体力学软件（FDS）模拟了某高校教学楼走廊中火灾和烟气的蔓延传播，通过算例分析了烟气温度场、可见度和CO体积分数等火灾过程参数的变化规律．研究结果表明，在火灾发生的4～5min时间内，走廊内的烟气温度、CO体积分数均达到人员安全的承受极限，能见度也将严重影响人员安全疏散．

To understand the evolution and the spread of fire smoke in the multi-storey teaching building, fire smoke spread characteristics for a university teaching building corridor were simulated by using the computational fluid dynamics software （FDS）. The fire parameters such as the smoke gas temperature, visibility and CO mass fraction variation were analyzed. The results showed that within 4 -5 minutes, the flue gas temperature and CO concentration of the corridor would exceed the bearing limit of persons, and the visibility would have significant impact on the evacuation.
