Modeling and Simulating of Airflow around Metro Train Head

The aerodynamic model of flow around metro train is built in this paper. The distributing of air flow around metro train head is calculated and analyzed based on aerodynamics of train and CFX. According to the result, the difference of the distributing of flow outfield and pressure field among these models are analyzed and compared. The proper parameters of contour design of streamlined train head were achieved. They provide theoretical foundation for the development of metro train contour design.
