Descripció del contingut i pla d'activitats:
The aim of this project is to proportionate active aerodynamics to BAIC supercar, the ArcFox-7. This project will be developed with the company QEV Technologies.
ArcFox-7 is an electric supercar presented at the Beijing International Automotive Exhibition 2016, it was developed by the Chinese BAIC BJEV and the help of QEV Technologies, who is now developing the new version of it.
Currently the ArcFox-7 does not implement any active aerodynamics, and there is not any study about it. The project will base its designs with the CAD of Solidworks, and the study and simulations with the CFD of ANSYS Fluent.
The project is organized around 4 phases:

1) Aerodynamic study of the actual version of the ArcFox-7.

2) Study of some active aerodynamic technologies.

3) Study of the implementation of the active technologies to the ArcFox-7.

4) Study and creation of a new active aerodynamic system for the ArcFox-7.



 
Overview (resum en anglès):

In this project an aerodynamic study is developed on a supercar, integrating different aerodynamic elements from the active aerodynamics. The model where this innovating technology is applied is the ArcFox-GT, a Chinese model by BAIC, but designed and developed by QEV Technologies in Barcelona.

At first instance, a review of fundamentals of fluid dynamics and conservation equations is made. The concepts and the basic forces of aerodynamics are detailed in the first chapter as well. The tool for the CFD (Computational Fluid Dynamics) is developed, Star-CCM+, used to model an adequate real scenario with a control volume, mesh and physic conditions. Appropriate wind tunnel modeling is understood by comparing the results of the model with the experimental results for two different configurations.

Once the wind tunnel configuration looks like reality, different active elements are designed and studied for different parts of the vehicle, from the front part to the back. The effect of these elements will help the dynamic behaviour of the vehicle in different situations. The principal objective of the model improvement will be the reduction of drag and lift coefficients.

A new version of the ArcFox-GT model is designed, named ArcFox+, it incorporates the different active elements previously designed. Studies are carried out with different distributions of these elements. Finally, studies for the minimum drag performance and the maximum downforce performance are developed.
