When a high-speed maglev train travels through a tunnel, sudden pressure changes are
generated in the tunnel, which have a negative impact on the comfort of passengers and the …

Urban electric multiple units (EMUs) is based on high-speed trains and metro vehicle
technology. Their design speeds are generally from 160km/h to 200km/h, which mitigates …

This study investigates the effects of bogie cavities and bogies on the aerodynamic
behaviour of a high-speed train (HST) using improved delayed detached eddy simulation …

Subway is an increasingly important means of transportation, the influence of the piston
effect on the train has attracted extensive attention of researchers. Nowadays, the train …

As train speeds continuously increase, the crosswind stability of high-speed trains (HSTs)
has been a prominent research topic. Benefiting from advances in railway technology, the …

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 …

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

Aerodynamic effects, including slipstream, piston wind, drag, and pressure wave, in the
tunnel caused by a metro train running between two adjacent platforms were simulated …

This study attempts to employ a multi-objective optimization algorithm and surrogate model
technology to deal with the reasonable matching of key aerodynamic parameters of railway …

The present work focused on the aerodynamic performance of double unit trains (DUT) and
traditional single unit trains (SUT) under crosswinds. The aerodynamic coefficient as well as …
