Abstract EN
The reverse force on the returning blade of a water turbine can be reduced by setting a deflector on the returning blade side of a rotor.
The deflector configuration can also concentrate the flow which passes through the rotor so that the torque and the power of turbine can be considerably increased.
The placing of Savonius in Darrieus rotor is carried out by setting the Savonius bucket in Darrieus rotor at the same axis.
The combination of these rotors is also called a Darrieus-Savonius turbine.
This rotor can improve torque of turbine.
Experiments are conducted in an irrigation canal to find the performance characteristics of presence of deflector and Savonius rotor in Darrieus-Savonius turbine.
Results conclude that the single deflector plate placed on returning blade side increases the torque and power coefficient.
The presence of Savonius rotor increases the torque at a lower speed, but the power coefficient decreases.
The torque and power coefficient characteristics depend on the aspect ratio of Savonius rotor.
