dc.descriptionClimate change is primarily driven by the use of fossil fuels. However, renewable energies, such as hydropower, cause deforestation and population displacement, and their energy usually does not reach remote areas. Gravitational Water Vortex Power Plants (GWVPPs) are a hydroelectric alternative that does not alter the course and flow of rivers and can be used in areas not connected to the power grid. This work focused on studying the influence of the inlet velocity on the morphology of water gravitational vortices (GWVs) and their fluid-dynamic properties such as pressure, velocity, and volumetric fraction. The methodology employed consisted of using the OpenFOAM CFD software to run the simulations, where the channel input velocity was changed and the contours of velocity magnitude, static pressure, and volumetric fraction in the basin were plotted. The results of the investigation showed that well-developed vortices were obtained from an input velocity of 0.03 m/s, while the higher speeds (0.05 m/s and 0.06 m/s) produced more uniform velocity magnitude contours. Although all vortices have an air core at discharge, high inlet speeds induce a greater likelihood of weak vortex formation. Finally, the conclusions of this work are that high speeds also lead to higher volume fractions inside the basin, which can be practical for water vortex power generation systems due to their higher inertia. The input velocity also influences the behavior of the height, curvature, and tangential speed of the free surface with the radius.en-US
dc.descriptionEl cambio climático es impulsado principalmente por el uso de combustibles fósiles. Sin embargo, las energías renovables, como la hidroeléctrica, causan deforestación y desplazamiento de la población, y su energía no suele llegar a zonas remotas. Las plantas de potencia por vórtice gravitacional de agua (GWVPP, por sus siglas en inglés) son una alternativa hidroeléctrica que no altera el cauce y caudal de los ríos y pueden usarse en áreas desconectadas de la red eléctrica. Este trabajo se enfocó en estudiar la influencia de la velocidad de entrada en la morfología de vórtices gravitacionales de agua (GWV, por sus siglas en inglés) y sus propiedades fluidodinámicas como presión, velocidad y fracción volumétrica. La metodología empleada consistió en el uso del software de CFD OpenFOAM para hacer las simulaciones, donde se cambió la velocidad de entrada del canal y se graficaron los contornos de magnitud de velocidad, presión estática y fracción volumétricas en la cuenca. Los resultados de la investigación permitieron encontrar que vórtices bien desarrollados se obtienen a partir de una velocidad de entrada de 0.03 m/s, mientras que las velocidades más altas (0.05 m/s y 0.06 m/s) producen contornos de magnitud de velocidad más uniformes. Aunque todos los vórtices tienen un núcleo de aire en la descarga, las velocidades de entrada altas inducen una mayor probabilidad de formación de vórtices débiles. Finalmente, se concluye que velocidades altas también conllevan mayores fracciones volumétricas al interior de la cuenca, lo cual puede ser práctico para sistemas de generación de energía por vórtices de agua debido a su mayor inercia. La velocidad de entrada también influye en el comportamiento de la altura, curvatura y velocidad tangencial de la superficie libre con el radio.es-ES
