Evaluating the Impact of Vehicle Speed on Thermal Behaviour of Brake Discs with DTDP Configurations

This study delves into the thermal behavior of automotive brake discs with Diamond and TearDrop Pillar (DTDP) configurations, focusing on the impact of varying rotational speeds on heat dissipation. Key topics include the transition from conduction to convection-dominated heat transfer, the influence of rotational speed on temperature distribution, and the optimization of brake disc designs for enhanced thermal management. The findings reveal that higher rotational speeds significantly improve convective heat transfer, reducing mean temperatures and enhancing cooling efficiency. At 60 rad/s, the DTDP configuration achieves a 13% reduction in mean temperature, demonstrating its potential to improve brake performance and longevity. This research provides valuable insights for developing more efficient and reliable braking systems in the automotive industry.
