Análise e confecção de um sistema de geração de energia elétrica usando o princípio de formação de vórtices através de um cilindro

Abstract

As human development advances, the demand for energy in the most varied forms grows very significantly. In search of small engineering alternatives, the field of renewable energies becomes the agenda in several engineering, looking for branches of generation on a decentralized scale. An interesting merit arises with the energy from the winds (wind), which several researchers tirelessly seek to use such energy with less robustness. Thus, as the conventional wind turbines contour method, a new model appears known as Bladeless Wind Turbine. Inserted in this perspective, the study of buses develops and analyzes the performance of an instrument, where the principle is presented by fluid mechanics, known as formation of vortices in a cylinder. Linked to this, a Piezoelectric Transducer (PT) of 27 mm in diameter was used, which was the generator of electricity. Such a component is capable of converting applied strain forces into electrical signals. Still, the use of magnetc devices is used, aiming to create a magnetic field with control of the influence of these in the system. For that, 4 different ones were proposed and verified throughout the research, where they consist of 3 different magnetic distances between the magnets, seeking the best range of interaction with the system, as well as influencing the experimentation of the material without magnetic. The distances were 12, 15 and 19 cm, for 3 different wind speeds, 3.49, 4.12 and 5.16 m/s. Thus, confronted with the results obtained, a situation of 19 cm of distance and 3.49 m/s occurred, in which the output voltage was 4.28 Vpp. Therefore, it is concluded that the developed experimental apparatus becomes more attractive for low wind speed ranges.
