The train-induced airflow in a tunnel has great significance for tunnel ventilation, fire rescue,
and equipment installations. In particular, the aerodynamic effects induced by two trains …

The slipstreams induced by high-speed trains under crosswind are studied in this paper by
the detached-eddy simulation (DES) method. First, the formation and development of the …

The pressure integral method is frequently used to obtain the train aerodynamic forces in
experiments, but the effect of the pressure pipe length on the pressure amplitude is not …

The cave is of great importance for the storage of equipment and to avoid having workers in
the tunnel, but it changes the tunnel section, leads to a change of slipstream and affects the …

The train-induced airflow in a railway tunnel is of great significance for tunnel ventilation, fire
rescue, and ancillary facilities overall. Previous research mainly focused on piston wind in …

This paper uses an improved delayed detached eddy simulation method to investigate the
unsteady flow features of the high-speed trains with various cavity lengths at Re= 1.85× 106 …

In this study, an improved delayed detached-eddy simulation method has been used to
investigate the aerodynamic behavior of the CRH2 high-speed trains (HST) with different …

In this work, the flow surrounding the train was obtained using a detached eddy simulation
(DES) for slipstream analysis. Two different streamlined nose lengths were investigated: a …
