Aerodynamic efficiency assessment of a cross-axis wind turbine integrated with an offshore deflector

Autor: Sam Saham, Saber Rezaey

Publikováno v: Heliyon, Vol 10, Iss 17, Pp e36412- (2024)

The present work examines the performance of an offshore cross-axis wind turbine (CAWT) with a flow deflector by integrating numerical and analytical methods. The deflector's geometry redirects flow in all directions, causing it to exit vertically an
