小尺寸房间及走廊内烟气流动规律模拟研究

Simulation study on smoke flow regularity in small size room and corridor

为研究房间-走廊内烟气流动规律,更直观准确地反映房间内发生火灾后烟气在房间及走廊中的流动状态,为人员疏散及救援提供技术指导,设计小尺寸房间及走廊条件下的烟气流动模型进行实验,并运用FDS火灾模拟软件对相同尺寸的房间及走廊模型烟气流动进行数值模拟。结果显示实验模拟与数值模拟的小尺寸房间及走廊烟气流动规律一致。根据实验及计算机模拟结果给出了火灾初期房间及走廊中人员疏散与自救的若干意见。

In order to research the smoke flow regularity in room and corridor, visually and truthfully reflect the state of smoke flow in room and corridor when the fire occurred in room, and provide the technical guidance for personnel in rescue and safe evacuation, the smoke flow model in small size room and corridor was designed, and the same size model of room and corridor was established to simulate smoke flow regularity by fire dy namic simulator FDS. The results showed that smoke flow regularity in small size of room and corridor by experimental simulation and numerical simulation was the same. According to the results of simulation, several advices about how people rescue themselves and take safe evacuation in room and corridor in ini tial fire was given.
