Description

<p>Aerodynamic forces acting on railway vehicles depend not only on the shape of the vehicles but also on types of infrastructure. In this study, the leading car of a train is simplified as a finite-length square cylinder; and the middle car is simplified as an infinite-length square cylinder. We conducted large-eddy simulations (LES) of the flow around the simplified vehicle model on flat ground, an embankment and viaducts. The LES results confirm that the side force coefficients of the vehicle models change depending on the type of infrastructure. We investigated the reasons why the type of infrastructures affected the side force acting on the vehicle in terms of the flow field.</p>
