The head/tail of a high-speed train has been designed in a streamlined way to achieve good
aerodynamic performance, which leads to the flow separation point moving close to the tail …

A diversion slot is one of the potential mechanical devices to reduce high-speed train
underbody aerodynamic resistance. This research aims to investigate the effectiveness of …

The high-speed railway bridge, accounting for over 50% of railway lines, plays an important
role in high-speed railways. When the train runs at high speed on these bridges, the strong …

The present study aims to assess the prediction ability of URANS (unsteady Reynolds-
averaged Navier-Stokes), SAS (scale-adaptive simulation), and IDDES (improved delayed …

The influence of upstream flow characteristics on the bi-stable flow structure in the wake
region of a simplified square-back heavy vehicle model at a Reynolds number of 2.7× 10 4 …

In the current study, the impact of various inflow conditions, including turbulent wind profiles

The influence of different inter-carriage gap configurations, including end wall geometries (3
cases) and gap spacings (0, 5, 8, 10, 15, 20, and 30 mm), on the aerodynamic …

The aerodynamic performance of four train models with different windshield configurations
(ie, internal and/or external) in three train marshalling modes (ie, 3, 6 and 8-car groups) was …

With the increasing speed of high-speed trains, abnormal vibrations in the tail car pose a
threat to its overall stability and running safety. In this study, the aerodynamic and multibody …
