Aerodynamics of high speed trains is very important from both the vehicle and infrastructure point of view. The study of the slip-stream effect on the track must be evaluated with a numerical approach since experimental data are too expensive. This study presents a DES modelling of an ETR500 high speed train, with the aim of finding a wind tunnel setup for measuring the aerodynamic slip-stream features. Numerical results are compared with experimental data measured on the Torino-Novara high speed line.

Abstract
Aerodynamics of high speed trains is very important from both the vehicle and infrastructure point of view. The study of the slip-stream effect on the track must be evaluated with a numerical approach since experimental data are too expensive. This study presents a DES modelling of an ETR500 high speed train, with the aim of finding a wind tunnel setup for measuring the aerodynamic slip-stream features. Numerical results are compared with experimental data measured on the Torino-Novara high speed line.File in questo prodotto:
