5th Oxford Tidal Energy Workshop (OTE 2016), 21-22 March 2016, Oxford, UKA Blade Element Momentum Theory (BEMT) model for ‘conventional’ 3 bladed designs of Tidal Stream Turbine (TST) is presented, with validations from scale model experiments carried out in a cavitation tunnel. Assumptions and limitations of the model are discussed in order to gauge potential use in assessing a high solidity, hubless and ducted TST design, which has been developed by OpenHydro. A number of adjustments to the model are considered, which are to be validated with fully blade resolved CFD studies and field data from a full scale device deployed at Paimpol-Bréhat, Brittany at the start of 2016 in collaboration with EDF.The Industrial Doctoral Centre for Offshore Renewable Energy (IDCORE) is funded by the Energy Technology partnership and the RCUK Energy Programme (Grant number EP/J500847/1)
