dc.description.abstract | [EN] Hydrokinetic turbines are presented as a future alternative for obtaining energy from water currents in a sustainable way. The increase in the efficiency of these turbines from different approaches constitutes a line of research in which numerous efforts are being concentrated. An experimental study is presented where the influence of the twist angle of the blades in the operation of the hydrokinetic turbines of the helical Darrieus type is analysed. The study is carried out in the water tunnel installed at the Polytechnic School of Mieres (EPM, University of Oviedo) equipped with the necessary instrumentation to obtain the characteristics of the evolution of the power produced with the rotational speed for different flow velocities and current blockages. Three models of turbine rotors were characterized with different twist angles (30º, 45º and 60º), under low current velocity and constant blockage conditions being able to know the conditions of maximum energy production, with clear differences between the cases. The results were also compared with the maximum power that can be recovered from a water current, defined by the actuator disc model for a uniform flow in channels, obtaining maximum efficiency values for the case of 45º twist angle. | es_ES |

Se presenta un estudio experimental donde se analiza la influencia del ángulo de torsión de los álabes en el funcionamiento de las turbinas hidrocinéticas de tipo Darrieus helicoidal. El estudio se realiza en el túnel de agua instalado en la Escuela Politécnica de Mieres (EPM, Universidad de Oviedo) que dispone de la instrumentación necesaria para obtener las características de evolución de la potencia producida con la velocidad de rotación para distintas condiciones de velocidad del flujo y bloqueo de la corriente. Se caracterizaron tres modelos de rotores de turbinas con distintos ángulos de torsión (30°, 45° y 60°), en condiciones de baja velocidad de corriente y bloqueo constante, pudiendo conocer las condiciones de máxima obtención de energía, con diferencias claras entre los casos ensayados. También se compararon los resultados con la potencia máxima que puede recuperarse de una corriente de agua, definida por el modelo del disco actuador para un flujo uniforme en canales, obteniendo máximos valores de eficiencia para el caso de 45° de ángulo de torsión. | es_ES |
