Performance Estimation of Ducted and Bare Tidal Turbines using CFD [PDF]

EPJ Web of Conferences
The main objective of this study was to investigate the effect of flow contraction created by a duct on the power generation of a tidal turbine prototype. As a preliminary step in the development of a full-scale floating bridge-type ducted turbine, aimed

An Experimental Study on the Darrieus-Savonius Turbine for the Tidal Current Power Generation

Journal of Fluid Science and Technology, 2008
The Darrieus turbine is popular for tidal current power generation in Japan. It is simple in structure with straight wings rotating around a vertical axis, so that it has no directionality against the motion of tidal flow which changes its direction ...

Optimal design of a tidal turbine

IOP Conference Series: Earth and Environmental Science, 2012
An optimal design procedure has been applied to improve the design of an open-center tidal turbine. A specific software developed in C++ enables to generate the geometry adapted to the specific constraints imposed to this machine. Automatic scripts based on the AUTOGRID, IGG, FINE/TURBO and CFView software of the NUMECA CFD suite are used to evaluate ...
