Repotenciación y optimización del túnel de viento del laboratorio de aerodinámica de la carrera de Ingeniería Automotriz

Abstract

This degree work was designed to re-enhance and optimize the wind tunnel at the aerodynamics laboratory of the Automotive Engineering career by digitizing the drag and real-time support during the development of aerodynamic test in the wind tunnel. For this purpose, the relevant literature was begun to better understand the operating principles of the tunnel and then implement the necessary instrumentation to monitor tests in the test section through a screen. The corresponding programming of the electronic circuit and the user interface design was done using the Arduino and Nextion Editor software respectively. Thereafter, tests were carried out on a scale vehicle model in order to analyze its aerodynamic efficiency. The calculated results are related to those obtained by aerodynamic study in the SolidWorks software to validate the study. Thus, it was possible to determine that while the vehicle has a better aerodynamic coefficient, the forces that act upon decline are therefore more ecological. Finally, the updating of the operation manual and maintenance of the tunnel was carried out. Therefore, it is concluded that the implementation of new instrumentation to the wind tunnel allows the digitization of data in real time and generating a better understanding of the effect of the air on the vehicle body. It is therefore recommended that aerodynamic tests be performed with a prototype to determine its efficiency before implementing any modifications to the respective vehicle.
