Abstract

This paper examines the performance characteristics of the Savonius windmill rotor under field conditions. Test data were collected on the speed, torque and power of the rotor at a large number of wind speeds for each of seven values of the rotor overlap ratio. The performance data of the Savonius rotor are also fully discussed and design criteria established.

      With regard to Savonius wind turbines, many researchers have significantly contributed to the improvement of the performance using experimental and numerical investigations to address various aspects of the problem. The influence of various design factors was investigated like the rotor aspect ratio, the separation gap between the rotor buckets, the variation of the bucket cross section, the number of buckets, the existence or elimination of rotor endplates, and the effect of bucket stacking [7–12]. In addition, many experimental and numerical studies have been conducted to analyze and visualize the flow field and pressure distribution in and around Savonius wind rotors [13–23].

      However, the concept of thick blades of different concave and convex surfaces started to be examined in recent publications. For the second technique, there is no consensus for the best value of the overlap and gap ratios as it varies in a board range [29,34–39]. Based on that, it is of great importance to investigate the overlap ratio and gap ratio to find the optimal values of both parameters.
