High-speed railway aerodynamics is the key basic science for solving the bottleneck
problem of high-speed railway development. This paper systematically summarizes the …

The coupling and complexity of railway train/tunnel system are further aggravated by
increasing train speed, which produces a series of aerodynamics problems, such as …

Falling concrete blocks are serious problems in high-speed railway tunnels, and they cause
delays of high-speed trains (HSTs) and even compromise driving safety. When HST-induced …

This investigation deals with numerical solution of complex aerodynamic interactions
induced by a high-speed train (HST) entering and passing through tunnels with a closely …

Alleviation of the pressure transients caused by high-speed trains intersecting in a tunnel
with partially reduced cross-section is investigated by numerical simulation. The RNG k-ε …

To investigate the fatigue behaviours of tunnel secondary lining under the aerodynamic
effects produced by the running high-speed railway (HSR) trains, we proposed a dual …

Subway is an increasingly important means of transportation, the influence of the piston
effect on the train has attracted extensive attention of researchers. Nowadays, the train …

This study attempts to employ a multi-objective optimization algorithm and surrogate model
technology to deal with the reasonable matching of key aerodynamic parameters of railway …

In this study, the aerodynamic performance of two trains that intersect inside a tunnel under
ambient wind conditions is investigated. A full-scale test is conducted to verify the …

Pressure gradient and micro-pressure wave induced by a high-speed train entering a tunnel
were investigated for the parametric design of equal-transect oblique tunnel portal. A moving …
