Projeto de um aerogerador de baixa escala com intensificador de potência

Abstract

Due to the great progress of the wind market in the world, several studies have been developing in order to optimize the performance of wind turbines. In this perspective, the present project was made for design aerodynamically a shrouded wind turbine of 300 W and to evaluate which benefits this new approach can bring in relation to the design of the same wind turbine without this equipment. For this, was studied the processes that involve the wind flow through a wind turbine, the performance of the aerodynamic profiles that form the blades and which features are influenced by the addition of the diffuser on the project. The methodology used to develop the wind turbine was the Blade Element Momentum (BEM), where it was possible to calculate values of active forces and generated power. Finally, we concluded that the shrouded wind turbine brought better results in values of generated power, the final power result was 5 times higher than the same turbine operating in an identical environment, but without the the diffuser.
