Simulated Calculation of Flow Distribution around Metro Head Based on CFX

This paper proposes a arithmetic model of flow distribution around metro head,calculates and analyzes distribution of air flow around metro head based on aerodynamics of train and CFX.According to the result,the differences of the distribution of flow field and pressure field among these models are analyzed and compared and the proper parameters of contour design of train head are achieved,which provides theoretical foundation for the design of metro train contour design.
