Desenvolvimento e análise de um microgerador hidrelétrico de vórtice

Abstract

The consumption of electricity by humanity has been growing continuously. To contribute to a greener future, improve network infrastructure and facilitate access to economical energy generation at a regional level, microgeneration is a little explored alternative. This study aims to design a simple-to-build microgenerator to generate energy with as few resources as possible, using the natural vorticity movement of water in an open volute. The mechanical design and manufacturing of the microgenerator will be structured according to mechanical manufacturing and assembly processes. For propeller turbine sizing, the rotor selection quantities will be presented. All necessary projects required by the Santa Catarina Environmental Institute (IMA) for the environmental exemption will be developed. It was then possible to verify the characteristics of the watercourse and then size the machine elements of the microgenerator. As an improvement to the project, a second model built mainly of concrete was proposed.It is therefore concluded that the installation of the microgenerator represents a promising opportunity to promote energy sustainability and local development.
