某火车站中庭不同排烟方式的效果比较
Comparison of performance between natural and mechanical smoke exhaust systems in a train station atrium
摘要：
以某火车站中庭为研究对象，采用FDS模拟软件对火灾烟气控制排放效果进行了模拟。结果表明，该中庭采用自然排烟时的排烟效果明显好于机械排烟。根据这一结论，提出了针对火车站类建筑防排烟设计的一些建议。

Abstract：
Taking a train station atrium as study object, simulates the fire smoke exhaust effect with FDS. The result shows that the smoke exhaust effect of natural ventilation is obviously better than that of mechanical ventilation. According to this conclusion, puts forward some suggestions for smoke control design of similar buildings.
