某地下车道火灾排烟有效性数值模拟研究

地下环形车道与隧道相类似,由于地下环形车道的特点以及长度较长,发生火灾时烟气难以排出,而且蔓延方向难以确定.借鉴防火分区的思想,通过分析提出了针对不同位置发生火灾采用不同排烟方案的纵向分段式排烟体系,并利用CFD技术对不同火灾场景进行模拟分析,证明了排烟方案的有效性.

Research on numerical simulation of efficiency of fire smoke exhaust of a underground driveway

Underground driveway is similar to a tunnel. Because of the characteristics of the underground driveway, and its long length, when fire happened it's difficult to let the smoke out, and can't determine the orientation of fire and smoke spread, the research of smoke control of the underground driveway is necessary. This paper referenced the idea of fire compartment. Longitudinal-segmentation smoke control was proposed which is based on the research of different fire scenes happened in different place. And then simulated and analyzed the different fire scenes by CFD technique, testified the efficiency of the smoke control project.
