Resumen
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

Resumen
Traditional Savonius wind rotor has simple structure and can operate in any wind direction. However, its aerodynamic efficiency is lower than other types. A novel S-shaped wind rotor with three blades is proposed in order to improve the aerodynamic performance. The blade of the rotor is composed of two opposing convex circular arcs and its shape likes an ‘S’. The flow characteristics of the rotor are studied and analyzed by computational fluid dynamics (CFD) numerical simulation method. The steady and transient performances are studied using SST k-ω model and sliding mesh method, and are compa

Resumen
An experimental performance study of Savonius small rotors is performed in this work. Two Savonius prototypes, two blades and the same aspect ratio, were constructed from vinyl polychloride and use different air flow. Experimental tests allowed the rotation speed of each rotor to be determined for different air flows. It is important to note that the average angular velocity of the smaller rotor is approximately fifty percent higher than the larger rotor. At the same time, the absorption torque on the rotor shaft was measured and the mechanical power of each Savonius wind turbine prototype was

Resumen
Savonius rotors are large and heavy because they use drag force for propulsion. This leads to a larger investment in comparison to horizontal axis wind turbine (HAWT) rotors using lift forces. A simple construction of the Savonius rotor is preferred to reduce the production effort. Therefore, it is proposed here to use single-segment rotors of high elongation. Nevertheless, this rotor type must be compared with a multi-segment rotor to prove that the simplification does not deteriorate the effectiveness. The number of segments affects the aerodynamic performance of the rotor, however, the resu

The Savonius-type rotor is a phenomenal rotor model applied to vertical-axis type hydrokinetic turbines, which use is quite popular even though its performance is considered lower than other rotor types. One of the advantages of the Savonius-type rotor compared to other types of vertical axis hydrokinetic rotors is that it is more effective in extracting hydrokinetic energy from low velocity water flows. This research aims to analyze the performance of the Savonius rotor by modifying the blade model by providing grooves on the concave side. Tests were carried out on a two-blade Savonius rotor

Abstract For harvesting wind energy, especially at low-velocity regions, Savonius vertical-axis wind rotors are usually preferred. Among other variants of the vertical-axis wind rotors, the Savonius rotor has become an attractive candidate as a small-scale stand-alone system due to its direction independency, ease of fabrication and the absence of yaw-mechanism. The present paper attempts to study the effect of corrugated blades on the performance of a conventional Savonius rotor. The corrugation is a bio-inspired concept derived from the dragonfly wings.
