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 …

The current mobility situation is constantly changing as people are increasingly moving to
urban areas. Therefore, a flexible mode of transport with high-capacity passenger trains and …

Double-unit trains increase passenger capacity but also increase energy consumption.
Therefore, research about the aerodynamic resistance of a double-unit train is of great …

High-speed trains experience a sharp transition to a strong crosswind environment when
running in a bridge–tunnel section due to the perennial prevailing crosswind in the canyon …

In this study, based on the SST κ-ω turbulent model, the IDDES method is used to simulate
the unsteady aerodynamic performance of trains with respect to different lengths of the …

The aerodynamic performance of stationary and moving CRH2c trains with or without a
windbreak wall under crosswind was simulated by DDES based on the SST κ-ω turbulence …

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 damage of lining widely exists in metro shield tunnels, which may weaken the structural
performance, affect the durability of the structure and even cause accidents. Investigation …

With increasing train speed, aerodynamic effects pose a safety risk for train operations,
especially for trains passing each other, the strong transient aerodynamic loads could result …
