Abstract
Many countries have been investing in wind energy, due to several benefits such as wide resource availability and low cost. Brazil has a remarkable wind potential and relevant market share in the global energy production, showing large evidence of research done in this field. Vertical-axis wind turbines (VAWTs) could be advantageous to traditional horizontal turbines (HAWTs) because of their less environmental impact and better performance for poor wind conditions, with special small-size applications for urban areas. In this work, a standard roof-top VAWT was chosen for power analysis in the city of São Carlos, based on the Multiple Streamtubes Model (MSTM). The output power obtained is similar to the real data provided by the manufacturer in respect to curve trending, but with variations in scale. MSTM overestimated the real results in about 70%, due to its simplifications and uncertainties in the turbine parameters. However, considering further improvements, this model could be quite useful for an initial analysis at a low computational cost required. Moreover, the selected turbine could supply significant part of the mean local energy consumption, for home or academic purposes.
