Análise da viabilidade técnica do aerogerador sem pás: um estudo de caso no Instituto Federal da Bahia – campus Jequié.

Abstract

With the constant increase in energy demand, the capacity for wind energy genera tion serves as an alternative to complement the energy matrix. Wind turbines typically have two or three blades, generating electricity with higher wind speeds and at greater heights. The bladeless wind turbine, Vortex Tacoma, is a new technology in development. It harnesses low-speed winds and has a compact structure, making it suitable for instal lation in urban areas such as houses and buildings. The equipment consists of a fixed base and a resonant mast. The non-aerodynamic design of the mast maximizes aerody namic instabilities and wind turbulence, improving energy capture, which occurs through the mast’s oscillation as the wind flows around the structure, creating a pattern of small von Kármán vortices. The objective of this study is to conduct a case study analyzing the technical feasibility of the bladeless wind turbine at the Federal Institute of Bahia – Jequié Campus for clean energy generation. The methodology includes the research and evaluation of relevant databases, conducting and analyzing the altimetry of IFBA, performing and evaluating simulations using Ansys Fluent, and analyzing and identifying technical feasibility. The results include the campus altimetry and wind speed exceeding the minimum requirement for turbine operation, as evidenced by Ansys simulations reve aling the release of vortices from these resonant masts. The selection of Vortex Tacoma was based on comparison with two other turbine models, standing out in terms of cost, maintenance, size, and power. Based on these simulations and the average data from the anemometer, the ideal arrangement for Vortex installation was identified. Furthermore, the use of multiple Vortex turbines in proximity increases energy gain due to the reduced space requirements and the vortex shedding wake effect. These preliminary results indi cate the technical feasibility of the bladeless wind turbine at the Federal Institute of Bahia - Jequié Campus, offering a potential solution for clean energy generation in urban areas. Further analysis and the implementation of multiple units could significantly contribute to the energy sustainability of the institution and the surrounding region
