摘　　要：地铁站台的气流流动属湍流流动,采用CFD对站台通风方式进行模拟时需要确定相关的边界条件和适用的湍流模型。通过对既有地铁站台气流状况的现场测试,获得了有参考价值的数据;建立了CFD模型。CFD模拟结果与测试数据的比较表明,所选的湍流模型能正确模拟复杂的站台气流流动。Airflow in underground railway station platforms is turbulent. Boundary conditions and proper turbulence model are required to determine when adopting CFD to simulate platform ventilation. Based on field tests and measurement of airflow of some existing platforms, obtains valuable data. Sets up a CFD simulation model. The comparison results of CFD simulation and field tests show that the selected turbulence model can correctly simulate complicated airflow in the platforms.
