A cooperation study between RTRI and SNCF on aeroacoustics: Numerical simulations and measurements of the aerodynamic noise of car body irregularities

Annoyances due to railway traffic noise are a very sensitive aspect concerning new high speed projects. Many studies have shown that aerodynamic noise becomes significant above 300 kph (without barriers). At the moment, for high speed trains, significant global reduction could hardly be achieved if the aerodynamic noise is not...
