  • GS43 Numerical Simulation of Underbody Flow of Simplified Railway Vehicle

抄録

Large-eddy simulation of flow around a train was conducted to investigate unsteady under body flows. The results of this study showed that large lateral velocity fluctuations were generated by two vortex streets along the train and that they propagated along the streamwise direction under the train.
