摘要
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。
By the fire analysis software (fire dynamic simulator) of large eddy simulation (FDS), studies the impact of ventilation velocity on smoke flow and temperature distribution under different fire power magnitudes, which is expected to provide related operation control parameters for daily management. The research reveals that the ventilation velocity of 2.5 metres per second is desirable when the fire power is around 20 MW in magnitude.
