As one of the main aerodynamic noise sources of high-speed trains, the bogie is a complex structure containing many components and the flow around it is extremely dynamic with high-level turbulence. Flow around a simplified bogie at scale 1:10 is studied numerically using computational fluid dynamics for comparison with experimental measurements. The upstream inlet flow is represented as a steady uniform flow of low turbulence level in the simulations. Following a rigorous grid refinement study, multi-block fully structured meshes are generated for all cases to improve numerical efficiency and accuracy. The aerodynamic and aeroacoustic behaviour of the flow past an isolated wheelset, tandem wheelsets and a simplified bogie are investigated.
