Aerodinâmica veicular aplicada a um protótipo da equipe Tuba Turbo

Abstract

The present work addresses the importance of aerodynamic analysis in optimizing the aerodynamic shell of the Tuba Turbo energy efficiency team's car. The main objective is to reduce drag coefficient, thereby enhancing the vehicle's performance in competitions. Initially, simulations were conducted to determine the drag coefficient of the current aerodynamic shell. Subsequently, improvement proposals were developed, focusing primarily on the rear part of the vehicle, where air recirculation is most significant and significantly affects the drag coefficient. Using software such as SolidWorks® for modeling the aerodynamic shell proposals, ANSYS® Fluent® for mesh generation and fluid dynamics simulation, and ANSYS® CFDPOST™ for results analysis, simulations were performed to assess variations in the drag coefficient with the proposed changes. The key findings indicate that all three new aerodynamic shell proposals, with the implemented modifications, exhibited lower drag coefficients compared to the current team's aerodynamic shell. The aerodynamic shell that achieved the lowest drag coefficient recorded a value of 0.0742.
