Performance of Combined Water Turbine Darrieus-Savonius with Two Stage Savonius Buckets and Single Deflector
Abstract
The objective of this study is to show the effect of single deflector plate on the performance of combined Darrieus-Savonius water turbine. In order to overcome the disadvantages of low torque of solo Darrieus turbine, a plate deflector mounted in front of returning Savonius bucket of combined water turbine composing of Darrieus and Savonius rotor has been proposed in this study. Some configurations of combined turbines with two stage Savonius rotors were experimentally tested in a river of constant velocity 0.8 m/s. The angle of deflector with respect to current flow influences the turbine perfomanace characteristics. The torque and the power coefficient of combined turbine with deflector increase for Savonius rotor mounted on the outside of Darrieus rotor. The optimum deflector angle of 30o gives a better performance of combined turbine.
