Effects of bottom deflectors on aerodynamic drag reduction of a high-speed train
Inspired by the fact that bogies and bottom equipment generally contribute a great deal of aerodynamic drag to high-speed trains, this paper puts forward a simple method of mounting some small deflectors before and/or after the bogie cabins to optimize ...
