Power estimates of an undulating membrane tidal energy converter

Implications of Tidal Phasing for Power Generation at a Tidal Energy Site

Spatial resource gradients have been observed at a number of proposed tidal energy sites. However, these gradients are typically quantified using the first or second moments (i.e., mean or standard deviation) of time series which obscures information about the co‐temporal amplitude and phase variation. These co‐temporal variations have a number of interesting implications for power production f...

The ‘Shoots Barrage’: An Indicative Energy Technology Assessment of a Tidal Power Scheme

Several tidal power schemes have been proposed for the River Severn Estuary between the South West of England and Wales. An indicative technology assessment has been undertaken in order to evaluate the so-called ‘Shoots Barrage’ over its foreseen lifespan of 120 years in terms of its cradle-to-site, operation and maintenance requirements. It would be located just upriver of the Severn road cros...

Investigation of the effect of geometry float body on the power of wave energy absorber converter using mooring catenary

This paper presents the effect of hydrodynamic parameters of the two-body converters of a point wave absorber on the amount of power output. This converter includes two submerged and floating bodies which are connected to the spring-damper system. The whole of the converter is connected to the sea bed by mooring catenary. The relative displacement of the floating body and the submerged body is ...

Atomization of an Undulating Liquid Sheet

This paper presents an experimental study devoted to the understanding of break-up mechanisms of liquid sheets. A shear instability develops at the interface liquid/gas resulting in an undulated motion of the liquid sheet. These undulations trig a Rayleigh-Taylor instability leading to azimuthal thickness modulations. A model including the development of both instabilities allows us to predict ...
