Análise do comportamento de coluna de iluminação autonoma solar

Abstract

In the elaboration of autonomous solar column designs, these will be subject to external effects from nature, it is necessary to evaluate these with a certain degree of reliability. However, the implications of these efforts present quantifications that are not very accurate quantifications and can generate unpredictable behaviors, promoting a lower than desired final performance, as with wind action. In this work, a study was carried out about the drag coefficient through the construction of a 1:30 scale model of an autonomous solar lighting column through 3D printing, to carry out experimental tests in a wind tunnel, with the objective of analyze the likely behavior of a real structure in the face of the efforts submitted. Also, a computational model to perform a numerical analysis in order to quantitatively compare the results obtained through two different solvers and two different turbulence theories compared to the experimental results. The computational studies done in this work employ finite element and finite volume models, developed in ANSYS®. The relevance of the results obtained are paramount for the company that manufactures the component, since corrections can be made in the project and consequently the life of the components will be longer, reducing possible replacement costs of parts that do not meet the desired goal.
