As more megacities emerge owing to urbanization and industrialization, the subway has
become the main public transportation mode worldwide, providing punctuality and …

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 …

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 …

Acceleration and deceleration are required for train operation, and the flow field around the
train shows strong unsteady characteristics during the acceleration and deceleration …

This paper aims to study a new connected structure composed of parallel headings and
cross passages, mitigating micro-pressure waves (MPWs) at the 400 km/h railway tunnel …

Mountain tunnel is inevitably connected to those canyon areas that could result in a very
special situation for the related designs. When the airflow goes through the canyon from an …

This paper provides an overview to all the published computational work in the Journal of
Wind Engineering and Industrial Aerodynamics in the field of train aerodynamics since …

Abstract A moving model (1/20 scale) was used to study the effect of high temperature at the
entrance of a tunnel on the aerodynamic performance of a high-speed train passing through …

Super-long metro tunnels, which allow two trains to simultaneously drive in the same tunnel
direction, have become increasingly important in urban areas where construction is …

The diffusion angle of the air jet and the optimal pitch angle (OPA) of the jet fan are studied
and compared through turbulent jet theory and FLUENT numerical simulation in this paper …
