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。
This article briefly introduces two main theoretical models of jet technology research. For a certain section of the subway tunnel with a parking line for its special area using Jet fan assisted ventilation design of smoke control program to simulate the fire exhaust conditions, test the parking lane and driving lane to form a double-hole airflow velocity, get the jet The distribution of wind speed along the exit of the fan changes the wind field characteristics of the two lines and the smoke control effect formed by the jet fan. The test results are validated for many subway fires with different auxiliary lines such as parking line, transition line and return line Tobacco control program design provides a reference for reference.
