    Diseño y construcción de un sistema de generación eléctrica utilizando energía hidráulica de canales de riego

    The objective is to design and build an electricity generation system using irrigation channels, in order to evaluate the potential that irrigation channels have generating electricity, as well as to find new renewable and sustainable energy sources. The irrigation channel that will be used in this research is the Huachi – Pelileo channel. The methodology begins with the collection of data on the speed of water and the flow that exists in the irrigation channel. The ANSYS software was used for the design of the turbine, in which the existence of cavitation in the turbine blades and the resistance of the turbine components were analyzed based on the Von Mises failure criteria. Then, the transmission system was designed based on the calculated rotation speed of the turbine and the speed required by the generator to operate. Finally, the construction and the evaluation of the generation system was carried out. The result obtained was a maximum power of 422.1 Watts in the test carried out in the workshop, in which the correct operation of the generation system was guaranteed. However, a simulation carried out in the SolidWorks software determined a maximum power of 1 kilo Watts. This value is due to the fact that the environment of the irrigation channel could not be recreated in the workshop.

    Diseño y construcción de una mini-turbina hidráulica tipo MICHELL – BANKI para ser instalada en canales primarios abiertos y generar energía mecánica
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2019) Ibañez Solis, Lenin Edwin; Escobar Luna, Luis Eduardo
    With the hydraulic data of the canal, the mechanical and hydraulic design of the Michell-Banki mini turbine was carried out. It was necessary to use several bibliographical documents such as published magazines and books, but the most important one was the "Design Manual, standardization and manufacture of equipment for small hydroelectric plants "published by OLADE. The parts of the turbine such as the blade, impeller, flange and shaft are clearly plastic materials because they will be subject to the action of water and thus extend the useful life of the components. For an optimal design an efficient alternative was considered, which is the manipulation of the turbine, this would have to be portable and as light as possible, for which it was decided to make a design with the mentioned characteristics. The turbine was built with a width of 49.7cm to optimize the material, a result table was obtained when the turbine was submerged at different heights, there it was found that the turbine has different efficiencies. When performing the tests, it was determined that there is an error ranging from 14% to 22% between the calculation of revolutions and torque produced in the software simulation and data obtained in the channel. Finally, it was found that the highest efficiency of the turbine is given to the output of each oval, this is because the water speed is 1.3m / s in a constant manner unlike the different parts along the channel , since, with a low level of water, the speed of the fluid also decreases.
