Resumo
Copyright © 2015 SAE International.This paper presents the different "gradients" of heat transfer coefficients found in a usual ventilated brake disc type. Although the conduction coefficient depends on the material characteristics applied, the convection and radiation coefficients changes as function of vehicle speed and brake temperature respectively. By comparing the coefficients magnitude orders of each surface and condition is possible to define the most favorable geometries for cool down the system.
