抄録

Flow through an air passage of ventilated automotive brake rotor affects the thermal energy dissipation from rotor into atmosphere. In the present work, a velocity profile around a ventilated brake disc was measured using a hot-wire anemometer in order to understand the statistical turbulent property of air passage flow. Three-dimensional velocity components were evaluated at 5 mm outside the disc edge by rotating X-type hot-wire probe. The probe was also tilted corresponding to rotational speed so that it could receive the maximum velocity from disc. The maximum value of both average and fluctuation velocity increased significantly than that of solid disc. The velocity fluctuation profile indicated asymmetric aspect in contrast to the average velocity profile. An empirical one-dimensional model was suggested for evaluation of flow through air passage. The predicted radius velocity agreed with the present experimental results by substituting local angular speed of disc into air circumferential velocity.
