Última Influence of the aspect ratio on the behaviour of an undulating membrane tidal energy converter ArchiMer Moreau, Martin; Trasch, Martin; Delacroix, Sylvain; Germain, Gregory. An experimental study of a 1/20th scale undulating membrane tidal energy converter (UMTEC) based on EEL Energy’s device is presented to assess the impact of the membrane's aspect ratio on its behaviour. The aim of this work is to study 3D effects on the machine to optimise the energy extraction. Five aspect ratios from 0.26 to 0.57 are tested at constant length, keeping other geometric parameters constant too. The mechanical energy of the membrane is conveyed above the free surface by a vertical cogwheel/chain assembly to be converted by an electric generator. After describing the experimental set-up, results are presented according to the reduced flow speed. Undulation dynamics and power conversion are analysed. This study highlights the effects of an...
