The cooling efficiency of automotive disk brakes comprises an important area of development, since the system performance is directly related to the overheating level that is being achieved during the braking period. The heat generation occurs during the conversion of kinetic energy into heat. After this process, it is crucial an effective thermal dissipation in order to assure the decay of temperature levels. Such thermal dissipation results mainly from the interaction of the brake components with the external airflow in the wheel arch, where there are the occurrence of heat transfer mechanisms including conduction, convection and radiation. In this sense, through the application of simulation models, it is possible to predict the thermal- structural behavior by combining solutions in the fluid dynamics and structural areas.
