半地下停车库自然排烟—补风方式的FDS数值模拟

FDS numerical simulation study of natural exhaust with natural air supply mode for semi-underground car park

以佛山某住宅小区的半地下停车库作为烟气控制研究的对象,通过火灾场景设计,对自然排烟—自然补风方式使用火灾模拟软件(FDS)进行模拟分析,并研究了发生火灾时的温度、烟气层的能见度及高度,结果表明,采光通风井自然排烟和高侧窗自然补风方式效果较好。

The natural exhaust through lighting-ventilation shaft with natural air supply was studied using FDS fire simulation software for a partially open-type underground car park of a residential district in Foshan. The temperature and visibility of smoke layer and interface height in case of the fire were investigated by simulation calculation using FDS fire simulation software. The results showed that the natural exhaust through lighting-ventilation shaft with natural air supply through high-side window modes is acceptable.
