In this study, a multi-objective optimization is performed to improve the performance of a
Darrieus vertical axis wind turbine (VAWT) at low tip speed ratios considering the …

A lift-driven vertical axis wind turbine (VAWT) generates peak power when it is rotating at
high tip-speed ratios (TSR), at which time the blades encounter angles of attack (AOA) over …

Vertical axis turbines, also called Darrieus turbines, present interesting characteristics for
offshore wind and tidal applications but suffer from vibrations and a lower efficiency than the …
