The efficiency of a turbine in a tidal channel
Chris Garrett,Patrick F. Cummins +1 more
TL;DR: In this article, the authors show that the fractional power loss increases from 1/3 to 2/3 as the fraction of the channel cross-section spanned by the turbines increases from 0 to close to 1.
Journal ArticleDOI
The prediction of the hydrodynamic performance of marine current turbines
TL;DR: In this paper, the authors developed a blade element momentum (BEM) model for the hydrodynamic design of marine current turbines, which includes routines for interpolation of 2D section data and extrapolation for stall delay.

Experimental study of the turbulence intensity effects on marine current turbines behaviour. Part I: One single turbine
Paul Mycek,Paul Mycek,Benoît Gaurier,Grégory Germain,Grégory Pinon,Elie Rivoalen,Elie Rivoalen +6 more
TL;DR: In this paper, the authors show that while the wake of the turbine is deeply influenced by the ambient turbulence conditions, its mean performances turn out to be slightly modified, which is crucial in the view of implanting second generation turbines arrays.
