    Abstract
  • Based on the 3D steady incompressible Navier-Stokes equation and the turbulent model of k-ε two equations, the aerodynamics properties of electric multiple units(EMU) CRH-2, running at 200 km·h-1 in strong wind, were numerically simulated by finite volume method(FVM). The constitutions of aerodynamic force and the influence of yaw angle on flow structure were analyzed, and the composings of aerodynamic force were studied. It is found that flow structure is very complex. Vortices emerge at both the leeward and tail of train on the condition of side wind. The vortices, which are formed and detached in the surface of train, change according to the variation of yaw angle. The constitutions and magnitudes of aerodynamic forces are different for whole train, first car, second car and third car. The variations of pressure field, side force and lift force along the fore-and-aft of train are uniform and complex. Analysis result indicates that the pressure has big influence on side force and lift force. The drag force is primary made of viscous forces for the streamlined design of train. On the condition of side wind, the security of first car decreases because the side force and overturn moment of first car are larger. 5 tabs, 12 figs, 16 refs.
