摘要
以目前工程上采用侧式疏散平台进行火灾人员疏散救援的地铁区间隧道为背景,使用三维CFD软件"STAR-CCM+"对隧道火灾纵向通风临界风速进行数值模拟研究。通过建立更为真实的隧道火灾场景,即将列车阻塞以及疏散门开启影响因素引入火灾计算模型,得到了不同热释放速率下的临界风速,从而为地铁工程排烟系统的设计提供参考。
Under the background of widely used subway tunnel equipped with lateral evacuation platform for the fire evacuation and rescue, the paper uses the new generation of CFD software "STAR-CCM+", applies the numerical simulation model to study the critical velocity of subway tunnel fires in longitudinal ventilation. The paper establishes a more real tunnel fire scene by introducing the influencing factors of blocked train and opened evacuation doors to the fire calculation model. At last, the paper obtains the critical velocity in the different heat release rate, which can provides reference for the design of the metro engineering exhaust system.
