Comparison of unidirectional and bidirectional airfoils in a tidal stream turbine
Giljarhus, Knut Erik Teigen; Owolabi, Jibola Obafemi; Frøynes, Olav Are (Peer reviewed; Journal article, 2022)Tidal stream turbines offer an attractive method for stable renewable energy generation. Due to the periodicity of the tidal stream, a tidal stream turbine can be designed to operate in a bidirectional manner, thereby ... -
Computational investigation of the aerodynamic performance of reversible airfoils for a bidirectional tidal turbine
Giljarhus, Knut Erik Teigen; Panahi, Ghazalsadat Shariat; Frøynes, Olav Are (Peer reviewed; Journal article, 2021)A reversible airfoil is an airfoil that has equal performance when the flow is reversed. Such airfoils are relevant for many different applications, including use in ventilation fans, helicopter rotors, wind turbines and ...
