Abstract

Vertical Axis Wind Turbines (VAWTs) can easily be mounted on building roofs and have more advantage

than Horizontal Axis Wind Turbines (HAWTs) in areas with turbulent flow. Savonius turbines have a lot of

advantages like high starting torque, simple in design, low price, compact in size, easy to install, capability

to operate independently in a wide range of wind directions and relatively low operating speed. In this study,

it has been investigated 6 different Savonius models. These models in two different blade types and 3

different blade numbers. The numbers of blade types have been selected as 2, 3 and 4 in turbine. Two

different blade types are drawn in Solidworks Program. All blade models are printed from 3D printer.

The experiments are carried out in the subsonic wind tunnel laboratory of the Faculty of Aeronautics and

Astronautics at Erciyes University. The test section of the wind tunnel has 15 Kw motor power. Test zone

inlet section is 0.57 m x 0.57 m and outlet section is 0.59 m x 0.59 m. The models have been mounted to the

torque meter. Measurements have been made at wind speeds between 1 m/s to 30 m/s with torque meter. The

performance values of each turbine have been measured. The most appropriate data has been obtained in

Type 2.
