摘　　要：以典型的北京地铁建国门站为研究对象,以Navier-Stokes方程为基础,引入了广泛应用的标准的k-ε湍流模型,建立用于求解典型地下铁道站台内流场的计算流体力学模型。采用计算流体力学场模拟软件ANSYS CFX为计算工具,建立典型地铁车站的物理与数学模型,以试验测试与大量参考文献综合计算的活塞风结果为计算边界条件,模拟计算城市地铁空调系统的气流场,得出地铁站台典型断面的温度场、速度场以及候车区关键位置的空气温度与速度分布规律。Abstract： This research mainly inforduces air conditioning system of the typical Beijing Jianguomen under- ground rail transportation hub for study. Based on Navier-Stokes equations and widely used standard k-ε turbulence model, it established computational fluid dynamics model for solving the flow field in urban underground rail trans- portation hub. Use computational fluid dynamics field simulation software ANSYS CFX as calculation tool, it estab- lished the physical and mathematical model of underground rail transportation hub. The boundary condition sets based on lots of literature. Based on the results of simulation, temperature and velocity distribution of typical sec- tions can be displayed. The simulation also shows temperature and velocity of key location.
