Abstract
The objective of this work is to develop a cooling analysis of the front brake disc of a formula SAE vehicle, comparing the behavior of different aerodynamic configurations, through the CFD method. The study of different disc cooling alternatives using CFD reduces prototyping costs, allows design changes more flexibly and reduces project development time, which is very eneficial for SAE projects. The methodology used was to compare four different aerodynamic configurations, one of the car without aerodynamic accessories, one with airfoils, another with a duct that takes air to the brake disc and finally one containing airfoils and the duct that takes air to the disc. Through wind tunnel simulations using ANSYS Fluent, for each aerodynamic configuration, the convection coefficient in the brake disc was obtained. Then, with the results of the transient thermal simulation, it was possible to compare the cooling time and evaluate the performance of each aerodynamic configuration. Concludes that the use of airfoils is more efficient in cooling compared to the configuration without aerodynamic accessories and the aerodynamic configuration that uses the duct that takes air to the disc is the one that promotes the greatest airflow in the inner region of the wheel, therefore it is the one that promotes more efficient cooling.
