The outer flow field over high-speed train is complex turbulent noW which
cause some unfavorable innuences to thc train and to the surmundings. so it is
attended and studied by researchers of the vehicle aerodynamics all the time.
Considering the characters of the viscoidal turbulent flow over high-speed train,
the computing model of the outer fiow field for high-speed train has been
established based on the incompressible fluid Navier-StOke...
