“…De la cual se puede notar la gran variedad de estudios acerca de estos dispositivos, los cuales aportan información sobre diferentes metodologías para el estudio de los OWSC en cuanto a la simulación numérica y a los parámetros y restricciones a tener en cuenta en la experimentación en canales de olas de los dispositivos. Así como estudios acerca de la geometría de la paleta, donde se concluye que, al tener geometrías de la paleta diferentes (Figura 18), el rendimiento del dispositivo o no se ve afectado en el caso de usar un solo OWSC [37], es decir, la potencia máxima es aproximadamente la misma cuando se tiene una aleta rectangular y cuando es una aleta en forma de cuña.…”

Los dispositivos de generación undimotriz son dispositivos que se encargan de transformar la energía proveniente de las olas del mar en energía eléctrica. Los sistemas de toma de fuerza se caracterizan por tomar la energía mecánica obtenida mediante el dispositivo undimotriz y facilitar su conversión a energía eléctrica. En este trabajo, inicialmente se realizó una búsqueda y evaluación de los dispositivos tipo oscilantes convertidores de energía de las olas y sistemas de toma de fuerza disponibles en la literatura para identificar su ventajas y desventajas con el fin de seleccionar los sistemas más indicados para el aprovechamiento del recurso undimotriz de Colombia. Los sistemas seleccionados corresponden a dispositivos undimotriz acoplados a estructuras fijas a la costa y sistemas de toma mecánica directa debido a que, estos presentan mayores ventajas en cuanto a su proceso de fabricación, puesta a punto, operación y mantenimiento. Finalmente se presenta un diagrama de flujo del proceso de diseño de estos sistemas.

“…They used both numerical methods and experimental testing in this case. Building on prior work, Kumawat et al [18] utilized a three-dimensional boundary element method to find the hydrodynamic coefficients of multiple flap-type seabed-mounted wave energy converters. In another study, they investigated the possibility of using a flap-type harvester along with a wind turbine.…”

This paper provides a study of a flap-type wave energy converter with a hydraulic power-take-off (PTO) system. This study includes the derivation of its equation of motion along with an analysis of natural frequencies of the device. A prototype was built using fillable cylinders and a series of experiments were performed in a wave flume. In these experiments, the pressure values of the hydraulic circuit were changed to investigate the optimal value for the system's pressure for a range of wave periods. The average wave-to-fluid efficiency (of about 15%) was achieved for a broad range of wave periods. It was also found that a 26% wave-to-fluid efficiency can be reached for waves with a period of 6.71 s. Based on the results of this analytical study, this device can be further optimized by filling its compartments with seawater.

Wave energy, a form of renewable energy, is derived from the movement of sea waves. Wave energy generation devices are technologies designed to harness this resource and convert it into electricity. These devices are classified based on their location, size, wave direction, and operating principle. This work presents the design of an oscillating device for harnessing wave energy. For this purpose, computational fluid dynamics and response surface methodology were employed to evaluate the influence of the percentage of the blade height submerged below the water surface (X1) and the distance from the device to the breakwater in terms of the percentage of the wave length (X2). The response variable studied was the hydrodynamic efficiency (η) of the device. Transient fluid dynamic simulations were carried out using Ansys Fluent software 2023 R1, with input conditions based on a wave spectrum characteristic of the Colombian Pacific Ocean. Analysis of variance determined that both factors and their interaction have significant effects on the response variable. Using the obtained regression model, the optimal point of the system was determined. Numerical results showed that the maximum η of the system was achieved when the device was submerged at 75% of its height and was positioned 10% of the wave length away from the vertical breakwater. Under this configuration, η was 64.8%. Experimental validations of the optimal configuration were conducted in a wave channel, resulting in a η of 45%. The difference in efficiencies can be attributed to mechanical losses in the power take-off system, which were not considered during the numerical simulations.
