This paper compares the performance of EARSM, SAS and IDDES turbulence models for
the aerodynamic problem of a high-speed train subjected to crosswind. These approaches …

When a train moves through the air, a region of air moves along with it at approximately the
same speed: this region of air is known as the 'slipstream'. Numerical simulations were …

In order to determine the effect of the coupling region on train aerodynamic performance,
and how the coupling region affects aerodynamic performance of the couple multiple units …

This paper considers the optimization of the nose shape of a high-speed train to minimize
the drag coefficient in zero-yaw-angle conditions. The optimization is performed using …
