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 …

Environmental health in subway stations, a typical type of urban underground space, is
becoming increasingly important. Ventilation is the principal measure for optimizing the …

High-speed railway lines are widely distributed worldwide. The surrounding wind
environment of such railway lines is complex, which significantly affects the safety of high …

Metro systems have been in use for over 150 years, and new metro lines are still being
constructed, either as new metro systems or as expansions of existing metro networks. In …

Windbreak (WB) and anti-wind open-cut tunnel (AOT) are two common windproof facilities
for high-speed railways in windy areas. This study aims to conducts a comparison of the …

As a fast and efficient short distance transportation means, the subway line has been built
and expanded in an increasing number of cities. The pressure in the tunnel fluctuates …

With an increase in train speed, the aerodynamic effects caused by the train could escalate,
especially for a train running in a tunnel. A number of large transient pressure waves are …

The understanding of natural ventilation in super-long tunnels can help to optimize the
design of ventilation systems and reduce energy consumption and maintenance costs. This …

In this study, the aerodynamic performance of full-scale trains of different lengths going
through or crossing each other in a tunnel was investigated using sliding mesh technology …

The running safety risk of a high-speed train (HST) deteriorates remarkably under crosswind
when the train drives into a bridge from a tunnel (OUT) or from a bridge into a tunnel (IN) …
