采用大涡模拟火灾分析软件(FDS)分析不同火灾功率时通风速度对隧道烟气流动及温度分布的影响,可为今后的日常管理提供相关的运行控制参数。研究表明,在20MW的火灾规模条件下,隧道通风速度以控制在2.5m/s为宜。
Using the large eddy simulation fire analysis software (FDS) to analyze the influence of ventilation velocity on the flow and temperature distribution of tunnel smoke with different fire power, it can provide relevant operational control parameters for daily management. The research shows that the tunnel ventilation speed should be controlled at 2.5m / s under the fire scale of 20MW.
