N2 - Brake system has an impact on the dynamic behavior of the vehicle, during brake episodes, the disc rotor can reach 900 °C, this rise of temperature could cause loss of brake response or failure of the braking system; to reduce overheating problems on disc rotors it is important to increase the air flux through the ventilation posts or vanes, which are between the braking surfaces of the disc brake rotors. Within this research, it is designed, produced and validated an internally ventilated disc brake rotor with a geometric configuration of 22 circular arrays of 9 ventilation pillars with drop tear shape of pillar posts, which increase air speed; to validate the model, it was produced by additive manufacturing, a prototype, to which, were carried out Particle Image Velocimetry tests on a wind tunnel to determine the distribution of air speed at the inlet and outlet of the disc, under three different rotation conditions: 187.2, 561.6 and 748.8 rpm. The results show that the geometric array has higher air speed in comparison with models, which have similar configurations.
