高层建筑条形走廊自然排烟效果的数值模拟与评价
Numerical simulation and evaluation of natural smoke exhaust for straight corridor in high-rise buildings
摘要：
采用场区模型模拟火灾发生时高层建筑条形走廊内的自然排烟过程,考虑了室外风向、风速、起火房间位置、走廊宽度和外窗尺寸、季节以及内走廊长度等因素对自然排烟过程的影响，对模拟结果进行分析并得出相应结论， 结果显示当内走廊长度超过30 m时，走廊内采用自然排烟不能保证人员的安全疏散。

Abstract：
Simulate the process of natural smoke exhaust for straight corridor in high-rise buildings with a field-zone compound model. Considers various components that affect the natural exhaust such as wind direction, wind speed, position of fire room, width of corridor, dimensions of exterior windows, season and length of corridor, etc. Obtains some conclusions through an analysis of the simulating results. The result shows that natural smoke exhaust should be used effectively in the corridor, the length of which is within 30 meter, to ensure people evacuate safely in fire building.
