Within the advances in Computer Fluid Dynamics algorithms and High Performance Computing, large clusters become available at low costs allowing virtual simulations that were not possible some years ago at reasonable costs and time. This work uses intensively this condition and applies these advances on brake system optimization. The methodology developed in the present work verifies the best angular position for caliper inside the wheel to reduce the rotor temperature during braking process such as downhill procedure. Thus, this method is applied to a mini-VAN vehicle, where the best position is found, based on two design parameters: rotor temperature and convection heat transfer coefficient. This study shows that the most suitable position for initial selection is the first one.

Environment concerns lead the automakers to invest resources and put research in engine downsize to reduce carbon emission. Turbo charge is a possibility due to its fuel consumption and emission reduction without compromise the performance. Nowadays, it is becoming common observe high performance small cars due to high torque and power available. In consequence, brake system need to dissipate more kinetic energy without adding mass or costs. Modern passenger cars require a high-speed brake system. To achieve proper brake system cooling, the rotor must be ventilated and designed to optimize the energy dissipated, which is generated by friction between pad and disk. Some approaches consider the rotor as a centrifugal air pump and the design rule is to improve the airflow inside the vanes. The approach considering a brake rotor similar to centrifugal air pump rotor may be considered as limited approach, once it simplifies the heat transfer phenomena inside chamber.
