Paper Details

This paper is an attempt to improve the thermal dissipation of commercially available disc brake rotors bybringing simple yet effective design changes. The basic idea behind is to improve the convective heat transfer area of therotor. The pads in the callipers of disc brake offer the retarding torque to stop the rotor. There is sliding friction betweenthe pads and the rotor. The frictional work done converts the kinetic energy or/and potential energy of the movingmember into heat. The heat generated in the process can be considered to be a source of heat flux for the rotor surface atthe contact surface of pads and rotor. The heat flux is calculated first. The rotor with the surrounding air in contact isessentially forming a case of forced convection. The heat transfer coefficient from a suitable Nusselt Number relation forthe case is obtained. Later, the existing and proposed rotors are modelled and analysed in suitable software package toobtain the temperature distribution. The reduction is the average temperatures of both the rotors suggest theimprovement in thermal dissipation analytically. The results are later validated in an experimental setup.
