Diseño y construcción de un dique mareomotriz didáctico y modelación del ducto de turbina

Abstract

Currently, the increase in emissions of CO2 and greenhouse gases produced by fossil fuels requires the use of alternative energy sources, which is generated by the unevenness of the tides storing water in a reservoir through a dam to transform the hydrodynamic energy into electrical energy. This project aims to study the variables of electric generation in a turbine duct such as: pressure, velocity and turbulent kinetic energy; using a 2D computational model in ANSYS Fluent and results of experiments by constructing a tidal module for didactic purposes. The experimental results show that there are variations in pressure at the inlet and outlet of the turbine duct due to the abrupt entry and wake leaving the propellant movement at the outlet; however, the fluid remains undisturbed in the converging zone until it reaches the propellant during the entire discharge of the fluid, generating a maximum electrical power of 2.022 W. When comparing the results of the computational model with the experimental data of pressure during the discharge of the fluid in four zones of the turbine, it has an average error of 3.06%.
