摘要
对武汉市红庙立交城市地下人行通道自然通风情况进行CFD模拟研究,将结果与现场实测数据进行对比,用于评价通风设计方案,为城市地下人行通道等工程通风设计提供经验。模拟采用标准辰e湍流模型作为通道气流模型,提炼实测通道温度、湿度及风速等数据作为边界条件。模拟结果表明,温度、湿度及风速等与实测数据基本吻合,标准辰e湍流模型可较准确地模拟城市地下人行通道的气流,CFD模拟可为城市地下人行通道通风设计服务。
To analyze the natural ventilation condition of Hongmiao interchange urban pedestrian underpass in Wuhan City, a CFD simulation study is conducted in this paper. And the results are compared with the field measured data to evaluate its ventilation design plan. The channel airflow model is the standard k-s turbulence model. Temperature, humidity, wind speed and other measured channel data are refined as boundary conditions. Simulation results show that temperature, humidity, wind speed and other data are basically coincident with the measured data. Standard k-e turbulence model can be used to simulate the airflow of urban pedestrian underpass accurately. CFD simulation can be used for the ventilation design of urban pedestrian underpass.
