Numerical Investigation on the Effect of the Azimuthal Deviation on Performance of Equal Speed Co-Rotating Double Rotor Small-Scale Horizontal-Axis Wind Turbine

Autor: Ahmed Morsi, Mohamed El-Dosoky, Othman Othman, Mohamed Ahmed, Ahmed Hamza Ali

Publikováno v: JES: Journal of Engineering Sciences, Vol 52, Iss 1, Pp 16-35 (2024)

A double-rotor setup is a promising approach to increase wind turbine power extraction. One common double-rotor configuration is the co-rotating-equal-speed arrangement. The performance of this setup is affected by the azimuthal deviation between the
