Aerodynamic analysis of a vehicle’s body for the competition Shell Eco-marathon

Resumo

The Shell Eco-marathon is a competition that challenges students around the world to make a High
Efficiency vehicle. One of the characteristics that influences the energy consumption is the body’s aerodynamics.
The main objective of this work is to choose, for the UTECO team of The Federal University of Technology –
Paraná, Guarapuava Campus, the vehicle body for the 2020 edition of Shell Eco-marathon Brazil. First, there is a
need to project three possible designs, using Autodesk Inventor software, and after approval of the design by the
team, they will undergo a simulation using computational fluid dynamics, with the software ANSYS Fluent. With
this, there is going to be an evaluation of the drag coefficient values obtained for the three different models. To
simulate the conditions, the results were based on the Reynolds-Averaged Navier-Stokes equations and the
turbulent model k-ε, after a statistical analysis, the model with the lowest drag coefficient was chosen. The
variables used on ANSYS, such as Temperature and Pressure were based on the City of Rio de Janeiro – RJ and
the meshing
