| Abstract: | This paper presents the numerical method of the flow field around high speed trains using Navier-stokes equations. The mixed difference scheme of the implicit and explicit al-gorithm is adapted to improve the convergence characteristic. The program system Train3D that is based on this method is developed. The aerodynamics and flow structures for high speed trains are obtained using this program system. |
