Predicting flow patterns that develop on the roof of high-rise buildings is critical for the development of urban wind energy. In particular, the performance and reliability of devices largely depends on the positioning strategy, a major unresolved c

Purpose This paper aims to investigate the variations in the flow fields induced by transition regions in the windbreak structures between the flat ground and the cutting along a railway and to propose mitigation measures to improve the windproof abi

A derailment phenomenon could take place on the windward side of a 120 km/h high-speed train when it runs by a breach, between two windbreak walls, subjected to a normal wind speed of 32 m/s. To study the safety of a high-speed train under different

The irregularities on trains bodies are normally ignored or greatly simplified in studies concerned with aerodynamics. However, surface roughness is known to affect the flow characteristics in the boundary layer near the wall, hence potentially influ

Field tests were carried out to measure the wheel-rail forces of a high-speed train passing by a windbreak breach with a crosswind speed and a train speed of 32 m/s and 120 km/h, respectively. Unst...

Crosswind stability of high-speed trains has been a prominent research topic for several decades, primarily motivated by the frequent rail-related accidents under strong crosswinds. In this study, the influence of different windbreak walls on train a
