Design and Aerodynamic Performance Study of a Butterfly‐Inspired Vertical Axis Wind Turbine for Urban and Aviation Zone Wind Energy Applications

Modelling and Simulation in Engineering, Volume 2025, Issue 1, 2025.
This study presents the development of a butterfly‐inspired vertical axis wind turbine (BAWT), integrating drag‐ and lift‐based mechanisms inspired by biological structures. By combining Savonius rotors, known for their self‐starting capability and torque stability at low wind speeds, with airfoil blades that enhance performance at higher tip‐speed ...

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 ...

Effect of Savonius blade height on the performance of a hybrid Darrieus-Savonius wind turbine

Journal of Mechanical Engineering and Sciences, 2019
A vertical hybrid turbine commonly consists of a Darrieus and Savonius rotor where the Savonius is inside Darrieus turbine. This paper describes the experimental study of hybrid Darrieus-Savonius wind turbines by variation in Savonius blade height.
