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 …

Among the various aerodynamic noise sources associated with high-speed trains, the bogie
regions, and particularly the leading bogie, contribute most to the overall noise. To control …

This study investigates the effects of bogie cavities and bogies on the aerodynamic
behaviour of a high-speed train (HST) using improved delayed detached eddy simulation …

The complex wake flow of a GTS (ground transportation system) model contributes to large
percentage of the aerodynamic drag force. Therefore, predicting accurate wake flow will …

The influence of ground clearance on the flow around a simplified high-speed train is
investigated in this paper. Four clearance heights are studied using IDDES. After a grid …

Based on 3-D, unsteady compressible Navier-Stokes equations and SST k-ω two-equation
IDDES turbulence model, the effect of cross passage on aerodynamic characteristics of …

The underbody flow of a truncated, 1: 10 scaled, CRH380A model is investigated at Re=
2.78× 10 5 in this paper. The large-eddy simulation (LES) is used to study the main features …

Transient numerical simulations were carried out by placing dimples at the top, sides and
bottoms of the tail car streamline area of a high-speed maglev train. The results of an …

This study numerically investigates the effects of Jacobs bogies on the aerodynamic
behaviors of a high-speed train using improved delayed detached eddy simulation (IDDES) …

With continuous increase in the train speed, the aerodynamic drag forces of high-speed
trains increase sharply in a square relationship. As an important source of train aerodynamic …
