A numerical study is carried out of three-dimensional airflow in the passenger cabin of high-speed electric train. The Reynolds-averaged Navier-Stokes equations are solved by using a FVM, which are coupled with the k-e turbulence model equations. Predicted velocity distributions are presented on several selected planes in the passenger cabin. The present three-dimensional simulations are found to show the overall features of the airflow in the passenger cabin fairly well.
