Flow Misalignment and Tidal Stream Turbines
Extensive Research and Development (R&D) within the tidal energy industry is pushing this sector towards commercial viability, with full scale prototypes starting to meet the challenges of the marine environment. This paper combines velocity data collected from Ramsey Sound (Pembrokeshire, Wales), with Computational Fluid Dynamics (CFD) to assess the impact of non-rectilinear flows on turbine r...
متن کاملParticle Dispersion under Tidal Bores: Application to Sediments and Fish Eggs
A tidal bore is a surge of water propagating upstream as the tidal flow turns to rising into an estuary with a tidal range larger than 5 to 6 m and a bathymetry that amplifies the tidal wave. The bore front is a shock characterised by a singularity of the free-surface and pressure and velocity fields. This study aims to characterise the tidal bore propagation and the induced turbulent mixing un...
متن کاملThe Effects of Array Configuration on the Hydro-environmental Impacts of Tidal Turbines
The economic viability of tidal turbines will require the deployment of multiple devices in array formations in a manner analogous to wind farms. This research investigates the effects of the configuration of a tidal turbine array, specifically the turbine spacing and capacity, on the hydroenvironmental impacts of the array. The hydrodynamic regime of the Shannon Estuary, a highly energetic est...
متن کاملTidal Turbines’ Layout in a Stream with Asymmetry and Misalignment
Abstract: A refined assessment of tidal currents variability is a prerequisite for successful turbine deployment in the marine environment. However, the numerical evaluation of the tidal kinetic energy resource relies, most of the time, on integrated parameters, such as the averaged or maximum stream powers. Predictions from a high resolution three-dimensional model are exploited here to charac...
متن کاملPerformance and Condition Monitoring of Tidal Stream Turbines
Research within the Cardiff Marine Energy Research Group (CMERG) has considered the integrated mathematical modelling of Tidal Stream Turbines (TST). The modelling studies are briefly reviewed. This paper concentrates on the experimental validation testing of small TST models in a water flume facility. The dataset of results, and in particular the measured axial thrust signals are analysed via ...
