摘要/Abstract

摘要： 为探明空气幕对地铁隧道内温度及流场分布的影响,通过火灾动力学求解器(FDS)研究不同火源热释放速率(HRR)、空气幕射流速度和射流角度下隧道内纵向温度、拱顶最高温度及流场分布。结果表明:火源HRR为10、15和20 MW时,空气幕射流速度至少为16、18和20 m/s才能保证烟气控制效果;当射流角度小于45°时,增大射流角度能加速拱顶温度衰减;当射流角度大于45°时,射流角度对拱顶温度衰减的影响很小;拱顶最高温度随着射流速度增大而减小,随着射流角度的增大而增大,射流角度通过影响火源与空气幕之间的旋涡来改变隧道内的温度分布。

关键词: 隧道火灾, 空气幕, 温度分布, 拱顶最高温度, 流场

Abstract: In order to explore influence of air curtain on temperature and flow field distribution in subway tunnel, longitudinal temperature, maximum temperature of vault and flow field distribution in tunnel under different HRR(heat release rates) of fire source, air curtain jet velocities and angles were studied by FDS (Fire Dynamics Simulator). The results show that jet velocity of air curtain should be at least 16, 18 and 20 m/s to ensure smoke control effect when HRR is 10, 15 and 20 MW. Increasing jet angle, in cases where it is smaller than 45°, can accelerate temperature attenuation of vault, but such effect will be little as it is more than 45°. Maximum temperature of vault decreases along with increase of jet velocity, but increases with that of jet angle which changes temperature distribution in tunnel by influencing vortex between fire source and air curtain.

Key words: tunnel fire, air curtain, temperature distribution, maximum temperature of vault, flow field
