dc.description | The present study was based on the analysis of the DU17DBD25 aerodynamic profile used in wind turbine blades. Simulations were carried out in the ANSYS Fluent program, varying the inclination angles of the wing profile between -20 and 20° and evaluating the drag and lift coefficients. Flow control devices called synthetic jets were implemented. The analyzes were carried out with jet and without synthetic jet. These results were compared with those obtained through the Blade Element Momentum Theory. The results of the simulations without synthetic jet were validated with respect to the values found in the literature, tending to behave similarly. A 10% improvement in the lift coefficient and a delay in the higher flow separation angle was obtained for angles of attack greater than 15°, which shows the increase in the performance of the wind turbine. | spa |
dc.description.abstract | El presente estudio fue basado en el análisis del perfil aerodinámico DU17DBD25 usado en aspas para turbinas eólicas. Fueron realizadas simulaciones en el programa ANSYS Fluent variando los ángulos de inclinación del perfil alar entre -20 y 20° y evaluando los coeficientes de arrastre y sustentación. Fueron implementados dispositivos de control de flujo denominados chorros sintéticos. Los análisis fueron realizados con chorro y sin chorro sintético. Estos resultados fueron comparados con los obtenidos a través de la Teoría del Elemento de Pala (Blade Element Momentum Theory). Los resultados de las simulaciones sin chorro sintético fueron validadas respecto a los valores encontrados en la literatura, tendiendo un comportamiento similar. Se obtuvo una mejora del 10% en el coeficiente de sustentación y un retraso en el ángulo de separación de flujo superior para ángulos de ataque mayores a 15°, lo que evidencia el incremento del rendimiento de la turbina eólica. | spa |
