Aeroacoustic Effect of Savonius Rotor Segmentation

Archives of Acoustics
Switching to renewable energy has been accelerated in recent decades due to the depleting fossil fuel reserves and the need to mitigate environmental and climate degradation. Wind power, especially in urban areas, has seen a significant growth. A critical consideration in the urban wind turbine installation is the noise impact on residents.

A study on increasing the performance of Savonius wind rotors

Journal of Mechanical Science and Technology, 2012
Savonius wind rotors with a vertical axis are not much preferred and used due to their lower aerodynamic performance than that of the other high-speed wind rotors. The present study is intended to increase the rotor performance of the Savonius wind rotor with theoretical method by focusing on a curtain arrangement as a wind deflector with a simple ...
