A contra-rotating marine current turbine on a flexible mooring : development of a scaled prototype
, 2008 The contra-rotating marine current turbine concept developed by the Energy Systems Research Unit at the University of Strathclyde is aimed at extracting energy in a wide range of water depths by 'flying' a neutrally-buoyant device from a flexible ...

A physics-based model for wind turbine wake expansion in the atmospheric boundary layer
Analytical wind turbine wake models are widely used to predict the wake velocity deficit. In these models, the wake growth rate is a key parameter specified mainly with empirical formulations.
