Projeto e construção de um mini túnel de vento didático de bancada experimental para estudos aerodinâmicos

Abstract

Wind tunnels are extremely important devices for simulation of flows for aerodynamic studies, facilitating analysis and providing practical support for a better understanding of disciplines such as fluid mechanics. In this way, this work aims at the design and construction of a small wind tunnel that will serve for didactic purposes of several areas such as mechanics, aeronautics, among others. For this, the development of an opencircuit and sucker-type device was defined, performing bibliographical analyzes and calculations to evaluate the best geometries of the components and methods to control the boundary layer and greater uniformity of the flow. After the sizing and modeling steps the process of constructing a prototype with low cost materials was started to verify the parameters approached in the project. Subsequently, the final wind tunnel was built based on the analysis of possible improvements of the prototype, performing load loss calculations to verify the drive and analysis of flows in test bodies, in order to confront with simulated results. Finally, the tunnel preparation plants were presented to serve as a base for undergraduate students and also as a didactic tool
