The impact of the MARINET initiative on the development of Marine Renewable Energy ArchiMer
Maisondieu, Christophe; Healy, Mark.
Marine Renewable Energy Conversion systems comprise wave energy and tidal stream converters as well as offshore-wind turbines for electrical generation. These technologies are currently at different stages of development but are mostly at the pre-commercial stage and require research to be undertaken at a series of scales along the path to commercialization. However each of these technologies also needs specific research infrastructures in order to conduct this research. The aim of the MARINET initiative is to coordinate research and development at all scales (small models through to prototype scales, from laboratories through to open sea tests) and to allow access for researchers and developers to infrastructures which are not available universally in...

Wake characterization of an undulating membrane tidal energy converter ArchiMer
Träsch, Martin; Déporte, Astrid; Delacroix, Sylvain; Germain, Gregory; Gaurier, Benoit; Drevet, Jean-baptiste.
Most of the research done on tidal energy focuses on marine current turbines. Therefore, tidal turbine’s wake is well-documented. The tidal energy converter studied here is based on the fluid-structure interactions that occur between a flexible membrane and an axial flow, resulting in an undulating motion that can be used to harvest energy. This device’s performance had been studied but it is the first time its wake is experimentally characterized from two-dimensional Particle Image Velocimetry (PIV) measurements. PIV is synchronized with a motion tracking system that gives information on trajectory and power conversion. Wake measurement gives access to velocity deficit, turbulence intensity and vorticity. Three configurations are tested in order to...
