摘要
本文简要介绍射流技术研究的两种主要理论模型。对于地铁某设有停车线区间隧道,针对其特殊区域利用射流风机辅助通风的设计烟控方案,在模拟火灾排烟工况条件下,测试停车线和行车线形成的双洞气流流速,得到射流风机出口沿程风速分布变化,对两条线路的风场特性及射流风机形成的烟控效果进行分析验证,测试结果对众多设有停车线、过渡线、折返线等不同辅助线路的地铁区间火灾烟控方案设计提供了参考借鉴。
Two main theoretical models of jet flow technology are briefly introduced in this article. For the smoke control design setting jet fans for the purpose of assisting ventilation at especial area in metro tunnel with stopping line, the flow rate in two tunnels formed by stopping fine and main line are tested funder the simulative condition of fire smoke exausting, and the flow rate distribution along the tunnel after the flow exit of jet fan is obtained. The flow field characteristic and the effects by jet fans in the two tunnels are analysed and verified through those test data. The testing result can provide references for fire smoke control design in those metro tunnels with stopping lines, transition lines, turn-back lines, etc.
