Abstract
Numerical simulations were carried out to investigate the flow velocity changes in the flow field due to the variation in the thickness of the upper part of the shroud tidal power generation system. In this study, it was performed under constant flow velocity condition. In addition, performance analysis of shroud was performed under the same conditions. As the height of the upper part increases, the flow velocity rate gradually increases, and it tends to decrease at a certain height. As a result of analyzing the shape of the blade and the shape of the blade combined with the shroud, the torque of the blade increased due to the increase of the flow rate by the shroud system. It is expected that the shape of the structure obtained by this study and the analysis of the flow velocity distribution in the flow field can provide the data necessary for the development of an efficient shroud tidal power generation system.
