Other AbstractNumerical simulation has been performed to investigate the flow around the high speed train under side wind conditions, and the yaw angle of 8.77癷s mainly focused. The model used in this paper is a scaled model in wind tunnel, with a scaled factor of 1:8. To compute numerically the complex flow structures, the three dimensional Reynolds-averaged Navier-Stokes equations, combined with the k-w SST model, were solved on hybrid grids using a finite volume technique. A comparison study between numerical results and experimental results has been conducted. Considering that the common CFD codes are still considered to be immature for the prediction of cross-wind stability, this paper delivers a comparative study between different commercial CFD software and tries to give best-practice recommendations for the investigated type of application. Furthermore, influence due to different meshes has been performed. Based on the best-practice results, the cross-wind characteristics of the high speed train have been mainly focused on. Both the fluid field characteristics and aerodynamic forces in cross-wind conditions are discussed.
