Abstract—Braking system is one of the important control systems of an automotive. For many years the disc brakes have been used in automobiles for safe retardation of the vehicles. During 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 airflow around the brake rotor and hence the aerodynamics is an important in the region of brake components. This project aims at maximizing the airflow distribution across the rotor for better heat dissipation and improving the cooling efficiency. A CFD analysis is carried out on the Skoda Octavia car braking system as a case study to make out the behaviour of airflow distribution around the disc brake components using FLUENT software. The result obtained from this analysis gives an insight idea of the airflow distribution around the brake rotor in order to minimize the temperature that affects the braking performance. Based on the results obtained, three new concepts were generated by incorporating air ducts guiding the air towards brake rotor to enhance the cooling effects. The results obtained for all the cases are analysed for effective cooling. From the results of temperature distribution it was observed that there is a considerable reduction in the max temperature generated during braking. 24 °C (611 °C to 587 ºC) decreased in maximum temperature for concept1 and 41 °C for concept2 by properly guiding air towards brake rotor and 110 °C decreased was observed in cocept3 is achieved.
