In recent years, high-speed railways in China have developed very rapidly, and the number
and span of the railway bridges are keeping increasing. Meanwhile, frequent extreme …

The effect of windbreak wall types on their windproof effects on trains has been
systematically investigated by comparing the flow field around a high-speed train behind …

To address the common issues and deficiencies associated with state-of-art static and
moving train wind tunnel test, this paper devised a novel test system for the aerodynamic test …

Unilateral vertical noise barrier (UVNB), bilateral vertical noise barrier (BVNB) and fully
enclosed noise barrier (FENB) are widely used along high-speed railways. The running …

This paper considers the optimization of the nose shape of a high-speed train to minimize
the drag coefficient in zero-yaw-angle conditions. The optimization is performed using …

Turbulent incoming flow conditions are closely matched to the crosswinds experienced by
trains in windy areas. Therefore, it is important to investigate how the turbulent inflow affects …

Coherent structures in surrounding flows around ground vehicles play an important role in
characterizing their aerodynamic features. However, due to restrictions of traditional reduced …

In this study, the delayed detached eddy simulation approach based on the shear-stress
transport κ-ω turbulent model was performed to simulate the unsteady aerodynamic …

Fixed-interval smoothing, as one of the most important types of state estimation, has been
concerned in many practical problems especially in the analysis of flight test data. However …

Reasonable gap spacings between adjacent train vehicle models are of great significance
for the data accuracy during a wind tunnel test. In this research, crosswind flows around …
