Abstract:
Based on the three-dimensional unsteady viscous incompressible Navier-Stokes equations and the standard turbulence model,using the Fluent computational fluid dynamics software,the situation that the highspeed train intersected in tunnel by the same speed was simulated.Two CRH380HL of same shape were arranged to intersect in the tunnel at four kinds of speed to simulate the changing process of aerodynamic forces,and the data of internal and external pressures of train body was collected.Using the formula to calculate the interior pressure of train body,this paper presented the passenger comfort evaluation of different train speeds.
