基于大型场所的FDS数值模拟分析

FDS numerical simulation analysis based on large-scale venues

使用FDS软件模拟了大型娱乐场所中发生火灾时烟气流动的三种情况,分别讨论了有无水喷淋作用,排烟措施及防烟分隔情况下的烟气蔓延情况,结果表明大涡模拟FDS可以用来预测大尺度较复杂结构中的烟气流动,能够清楚地显示流动情况。

This paper simulates three kinds of fire smoke flow in large-scale recreational venues by using FDS software, respectively discuses the spray role with and without water, smoke emitted measures, and smoke pervasion condition in the condition of smoke prevention. Results show that： Large-Eddy Simulation（LES） FDS can predict smoke flow with large size and complex structure, and can clearly demonstrate smoke flow condition.
