摘要:
高层建筑发生火灾时,烟气对人员的生命安全有着非常大的威胁,因此有效地控制烟气在建筑物内的扩散对于人员的逃生是非常重要的。通过高层建筑内烟气流动的数学模型,采用kε两方程三维紊流模型对高层建筑火灾时排烟口布置于走廊顶棚和走廊侧壁时的机械排烟进行模拟。结果表明,排烟口的布置方式不同对排烟效果的影响很大。排烟口置于顶棚时比排烟口置于侧壁时排烟效率高近10%,走廊内危险性低。在进行排烟设计时应优先考虑将排烟口设置在走廊顶部。
Abstract:
In highrise building fires, smoke has great threat to peoples life security in the building. So, it is very important to control the diffusion of smoke in the building. Mathematic model of smoke flow in highrise building and threedimension turbulence model with two equations were used to simulate the efficiencies of mechanical smoke exhaust on different arrangement methods of smoke vent. The results showed that different arrangement methods of smoke vent have great influence on smoke exhaust effect. Compared with the method that set smoke vent on the side wall of the corridor, when smoke vent is set on the top of the corridor, the efficiency of mechanical smoke exhaust was about 10% higher, and had a low risk in the corridor. While designing smoke exhaust system, setting smoke vent on the top of the corridor is a prior consideration.
