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 presentation by the University of Manchester describes development of a CFD model of the TGL turbine and a detailed study of transient flow and loads. It coversMD1: Development of a CFD model of the TGL turbine at the EMEC site.Methods:Sliding Mesh Method developed for RANS and LESSynthetic Eddy Method used to represent depth profile of mean and unsteady flowLES with sliding mesh method and SEM inflow to predict 1 MW turbine loadsFindingsAccurate prediction of power and thrustMeasured shear significantly affects cyclic blade loadingLES with SEM inflow predicts blade root bending moment affecting fatigue designAim Achieved: To establish capability of CFD for unsteady load prediction in realistic flowsLessons and Next Steps
