高层建筑走廊机械排烟的数值模拟研究
Numerical simulation of mechanical smoke exhaust in corridor for high-rise buildings
摘要：
采用场—区复合模型模拟起火层内的烟气运动过程，分析了走廊通道内三种机械排烟方案的烟气控制效果。模拟结果表明，与排烟量相比，排烟口的位置和数量对排烟效果的影响更大；排烟口应尽量远离疏散出口。

Abstract：
Simulates smoke movement in corridor with a field-zone compound model. Analyses smoke control effect with three schemes. The results show that the amount and position of exhaust smoke outlet have more significant influence on exhaust effect in contrast with the exhaust smoke rate, and exhaust smoke outlets should be far from escape exits as possible.
