Abstract As the velocity of a train increases, the corresponding air pumping power consumption of the brake discs
increases proportionally. In the present experimental study, a standard axle-mounted brake disc with circumferential pillars was analyzed using a 1:1 scale model and a test rig in a wind tunnel. In particular, three upstream
velocities were selected on the basis of earlier investigations of trains operating at 160, 250, and 400 km/h, respectively. Moreover, 3D steady computational fluid dynamics (CFD) simulations of the flow field were conducted to
compare with the wind tunnel test outcomes. The results for a 3-car train at 180… More >
