One of the key developments of the marine energy industry in the UK is the demonstration of near commercial scale devices in real sea conditions and the collection of performance and environmental data to inform permitting and licensing processes. The ETI’s ReDAPT (Reliable Data Acquisition Platform for Tidal) project saw an innovative 1MW buoyant tidal generator installed at the European Marine Energy Centre (EMEC) in Orkney in January 2013. The project demonstrated the performance of the tidal generator in different operational conditions, aiming to increase public and industry confidence in tidal turbine technologies by providing a wide range of environmental impact and performance information, as well as demonstrating a new, reliable turbine design
This document provides an outline of turbulent flow characterisation techniques relevant to the marine tidal generation industry and their applicability to the numerical simulation activities within the ReDAPT project. The report describes options for characterising turbulent flow and the types of parameters that would ideally be measured. The report concludes with an outline of the near-field flow measurements that will be undertaken around the TGL device in the Fall of Warness to feed into the turbulence models.
