Resumo
Alternative systems of power generation has become increasingly intense in Brazil, and generation using wind power arouses great interest due to the good existing wind potential in coastal regions of the country. As part of the research in this area in the Amazon, Professors and Researchers at the Federal University of Pará and other research centers have developed mathematical tools for optimal aerodynamic design of wind turbines with and without diffuser, which have been well accepted in the scientific community. Despite these professionals to develop scientific work of international significance, their laboratories do not have adequate apparatus and instrumentation for testing dedicated to the development of research and wind systems technologies. Thus, in this work it was performed the design and construction of an open-circuit low-speed wind tunnel in a blower type with 600 x 600 mm² test section, contraction ratio equal to 9 and maximum speed in the test section of 30 m/s. The resulting tunnel showed to have a good flow quality in its test section with a well-developed speed profile in both vertical and horizontal directions.
