Braking is one of the important functions of a vehicle. It is very important to design the braking system in such a way that the vehicle remains safe at the braking conditions. The disc brakes are commonly used in most vehicles. When the brakes are applied high amount of energy is dissipated from the disc brakes. The efficiency of the dissipation of the brakes defines the safety of the braking system. This depends on various parameters like the material, ambient temperature, braking power, heat transfer coefficient of the air on the surface of the disc brake. A computational fluid analysis (CFD) and thermal analysis are performed on the disc brake to study the heat dissipation characteristics of the designed disc brake. The surface heat transfer coefficient of the disc brake, velocity is studied in the ANSYS FLUENT solver and the structural-thermal analysis is performed in the ANSYS Workbench in which deformation and final temperature are calculated.
