“…Other works point out the advantages of the sources studied here, but in an individual way, as for example, the studies 18,25,26 analyze different characteristics of hydraulic energy, carrying out comparative studies on this same source. Reference 27 addresses the economic issues related to wind energy, and the References 28,29 make comparative analysis on solar energy.…”

“…As already discussed in the previous section of this paper, Brazil is a country with a rich hydrographic basin that presents a great opening for MG and DG. Ahmed et al, 25 in a study that the author proposes a method of optimizing the use of low-head hydroelectric potential with a focus on the socioeconomic development of his region, and reports a study carried out in nine hydrographic basins in Brazil. The study that aimed to identify the optimal hydroelectric potential of these nine basins resulted in an energy potential that exceeds 2 (GW), giving about 27 (TWh/year).…”

Brazil has one of the richest river basins in the world and an energy matrix based mostly on hydroelectric power. Current national policy is increasingly promoting renewable sources like wind power and solar photovoltaic power. Technologies used in generation energy via hydro, wind, and solar sources can be employed in decentralized generation. This study describes a turbine for hydro energetic use in flow sites with heads up to 2.5 (m). A hydrodynamic study was performed using computational fluid dynamics (CFD) analysis to evaluate the performance of this turbine. For this, a three-dimensional model of the turbine was considered, consisting of three computational domains, using periodicity to decrease the computational cost. The variation of the angular velocity and the volumetric flow were the boundary conditions. The turbulence model used was the shear stress transport. The draft tube geometry was modified according to the results of the CFD analysis. The efficiency and performance of the turbine improved from 79% to 80% as a result of this modification. A case study was conducted for a comparative financial analysis of the turbine proposed in this paper, with wind power and solar photovoltaic decentralized generation in Brazil.
