Effect of duct geometry on the performance of horizontal-axis marine current turbines
Abstract
The systems used in EMR applications are strongly impacted by the severe environmental conditions that remain poorly characterized during their installation, operation or maintenance phase. The optimization of their functioning and their dimensioning can only be done by mastering the interaction between the environment and the structures of the systems. The purpose of this study is also to investigate the effect of duct geometry on the hydrodynamic performance of the turbine. The numerical results show that the addition of duct improves the efficiency of the turbine.
