Braking system is one of the important control systems of an automotive. For many years, the disc brakes have been used in automobiles for the safe retarding of the vehicles. During the braking enormous amount of heat will be generated and for effective braking sufficient heat dissipation is essential. The thermal performance of disc brake depends upon the characteristics of the airflow around the brake rotor and hence the aerodynamics is an important in the region of brake components. A CFD analysis is carried out on the braking system as a case study to make out the behaviour of airflow distribution around the disc brake components using ANSYS CFX software. We are interested in the determination of the heat transfer coefficient on each surface of a ventilated disc rotor varying with time in a transient state using CFD analysis, and then imported the surface film condition data into a corresponding FEM model for disc temperature analysis.

“…All three variations have the advantages of low cost and fast assembly, but they also have some disadvantages, i.e., single-point measurement, distance from the contact, etc. [18,19]. (b) Of the non-contact methods, a temperature measurement with a pyrometer is the most frequently used.…”

“…Accordingly, three types of equipment need to be considered: thermocouple, radiation pyrometer and thermoscanner. (a) The most common method for temperature measurement in braking technology is to use thermocouples (e.g., NiCr-Ni) [19]. Thermocouples can be applied as permanently fixed sensors in the disc or in the pad and/or as the sliding sensors at the disc surface.…”
