Pombo, (Editor), "Proceedings of the Second International Conference on Railway Technology: Research, Development and Maintenance", Civil-Comp Press, Stirlingshire, UK, Paper 27, 2014. doi:10.4203/ccp.104.27

Keywords: inflow profile, CWE, self-sustainability, cross-wind, RANS, high speed train.

Summary

The inflow profile and its sustainability which have been widely researched in computational wind engineering (CWE) are rarely reported in the train aerodynamics community. By reviewing the related research in CWE, the implementation and verification of inflow profile horizontal homogeneity and selfsustainability have been done in a 2-D flat ground wind field numerical simulation. Finally, the effects of different cross-wind conditions, including gradient wind profile and uniform inflow with various turbulence intensity, on mean force applied on the high speed train have been compared and analysed. During the numerical computation, the two-dimensional RANS equations, combined with the sst-kw turbulence model were solved on a structured grid using a finite volume technique.
