(EN) AERODYNAMIC MODIFICATION OF A RING FOIL FOR A FLUID TURBINE
Abrégé
(EN)

A ring fluid foil including a modified trailing portion for a shrouded fluid turbine and shrouded fluid turbine including such ring fluid foils are described herein. The modification of the trailing portion increases flow turning by the fluid foil without, or with reduced, boundary layer separation on a suction side of the fluid foil.
