| Abstract |
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 represents deliverable MD1.4 and describes the application of EDF’s open-source CFD solver Code_Saturne to large-eddy simulations (LES) of a full-scale tidal-stream turbine (TST). All simulations were performed with realistic approach-flow mean-velocity profiles. The objective of the work was to supplement this with realistic approach-flow turbulence and to extract frequency spectra of the fluctuating loads. LES was conducted with both zero inlet turbulence and with a fluctuating velocity field synthesised from the stress profiles and length scales generated by a fully-developed channel-flow simulation. Turbulence profiles were further scaled to represent field measurements more accurately. The simulations follow on from Reynolds-averaged Navier-Stokes (RANS) computations reported earlier in MD1.5, but allow a more comprehensive evaluation of fluctuating loads on the turbine |
