Abstract
The use of diffusers around wind turbines, especially small ones, is important because it can maximize the kinetic energy extracted from the wind. In isolated regions, turbines with diffuser are indeed required due to typically low wind speeds. Regions like this are commonly found in the Amazon and are characterized by difficulty in accessing electricity. This work concentrates on a method to design a small wind turbine able to attend the conditions and characteristics of low wind speeds, typically found in Amazon. A study of a turbine shrouded by a diffuser is made in this work. In this sense, a numerical analysis is carried out in this paper, in which a small diffuser is designed. We verified an increasement of the velocity profile through the rotor, under the influence of the diffuser, which provides improvements on the turbine performance.
