Noise production by a Savonius type wind turbine- a comparison between single and five segment rotor.

The following data set contains acoustic evaluation results from experimental studies performed on Savonius wind turbine. 

Noise from a typical single segment Savonius wind turbine has been compared to that of its five segment counterpart. This comparison is mainly conducted for three case:

1. when rotor is loaded (giving us max coefficient of performance)

2. when the rotor is not loaded (free rotation)

3. when the rotor is stopped. 

Power characteristics of the two rotors have also been plotted, allowing to establish a comparison between noise and power produced.
