摘要
了解认知隧道内的流体力学的特点对于隧道火灾的研究和隧道安全建设有着非常大的意义。为了对隧道火灾的特点进行研究,我们使用商用CFD程序STAR-CD对速度场和压力分布进行了数值模拟。模拟过程中在同一入口位置的情况下改变四个出口位置,出口位置与模具高度的数值对别分别为L/H=0,0.375,0.75,1.125。同时还介绍了对于火灾救援和人员疏散的有效措施。
Understanding the characteristics of flow in tunnel fire is very important for tunnel safety.The characteristics of tunnel fire were analyzed.A commercial CFD program,STAR-CD,was used to examine the velocity fields and the pressure distributions in numerical simulations.The spreading rules and characteristics with four different out vents,each dimensionless L/H ratio of which is 0,0.375,0.75 and 1.125,respectively as the locations of each outlet are away from the vertical centerline through the inlet.The effective measures of fire rescue and crowd evacuation were also described.
