| 摘 要： | 应用火灾动力学分析软件FDS（version4．0），以Navier-Stokes方程为基础，引入浮力修正的κ-ε湍流模型、湍流燃烧模型和辐射换热模型，建立了适用于描述隧道内烟气温度分布和气流流动的计算流体动力学模型．针对设置有顶棚烟道和未设置顶棚烟道的公路隧道，在发生火灾时的温度场和CO的分布进行模拟研究．通过对比分析，得出了设置烟道有利于降低公路隧道发火灾的温度的结论．

| Abstract: | By means of a CFD simulative analytical method, FDS （Fire Dynamic Simulator version4.0） is adopted to analyze the temperature field distribution in tunnel fire without flue and with flue. The result shows that when a flue is set up, the temperatures of positions downstream, upstream and above the fire are much lower. |
