Wind Tunnel Testing on Crosswind Aerodynamic Forces Acting on Railway Vehicles

Autor: Hyeok-bin KWON, Seong-won NAM, Won-hee YOU

Publikováno v: Journal of Fluid Science and Technology, Vol 5, Iss 1, Pp 56-63 (2010)

This study is devoted to measure the aerodynamic forces acting on two railway trains, one of which is a high-speed train at 300km/h maximum operation speed, and the other is a conventional train at the operating speed 100km/h. The three-dimensional t
