摘要
针对体育场馆超大空间的结构特点,分析影响自然排烟因素以及烟气蔓延情况。介绍烟气流动特征,分析自然排烟系统性能方法,描述了烟气层的相关计算机模拟计算,汇总分析了不同火灾场景条件下烟气蔓延过程的计算结果。
The factors affecting the natural smoke extraction and smoke spread according to the structural characteristics of the large space of the stadiums were analyzed.Smoke flow characteristics,natural smoke extraction system performance methods and computer simulations of smoke layer were described.Summary analysis of smoke spread process under conditions of different fire scenarios were showed.
