Trabalho de Conclusão de Curso (Graduação em Engenharia Mecânica) - Centro de Tecnologia, Universidade Federal do Rio Grande do Norte, Natal, 2019.https://repositorio.ufrn.br/handle/123456789/42899Faced with the great demand for clean and renewable energy sources, wind energy has become an important source. In order to increase efficiency in the use of wind energy, it is necessary to develop studies in the area. The use of prototypes is the best way to study this subject, but it has the drawback of the high cost. With this in mind, this work was developed with the objective of designing a wind turbine rotor on a reduced scale to minimize production costs and tests, so that it can meet the basic needs of a residence away from the city, such as its lighting, analyze the behavior of the flow that acts on it using CFD and build it via 3D printing. For this, the concepts of fluid dynamics were applied to perform aerodynamic studies of wind turbine blade profile. Designed blades using the Blade Element Momentum (BEM) methodology, which requires the development of a computational routine to obtain geometric profile data. Using the data provided by these algorithms and a modeling software, the definitive rotor geometry, a 3D model, was created. This model was used to perform a flow simulation using CFD techniques. This allowed us to visualize the velocity fields, pressure fields acting on the virtual model that validates the rotor geometry, and then the model was sent for construction, in a 3D printer at the university itself. The prototype follows the objective of serving as a model for future projects.Aerogerador, BEM, rotor, eólica, simulação.Wind, turbine, BEM, rotor, simulationbachelorThesis
