About the Project

This pioneering research project has strong relevance to the field of Marine Renewable Energy. Many nations are committed to reducing carbon emissions worldwide. Widening the Marine Renewable Energy base has high priority in the Energy agenda of the UK and other countries in Europe and overseas. The potential of low-environmental impact tidal current energy (TCE) in North-West Europe is one of the largest in the world, but its exploitation is growing slowly, due to the high wholesale price of TCE.
To reduce the cost of TCE, this project aims at analysing and reducing the energy losses in arrays of tidal current turbines due to interactions of the wakes shed by front-row turbines and the downstream turbines, and also variations of the current speed due to wake-blockage-induced effects.
The research is based on the use of Navier-Stokes Computational Fluid Dynamics (CFD) and advanced turbulence analysis approaches, ranging from Reynolds-Stress models to hybrid methods suitably combining the computational strengths and accuracy of the Reynolds-average Navier-Stokes and Large Eddy Simulation methods. Due to the use of turbine-resolved models, most CFD simulations will be large and use significant high-performance computing (HPC) resources at world-leading supercomputing centres. The main deliverables are new reliable knowledge of tidal array energy efficiency and hydrodynamic loss mechanisms, and a new open-source CFD framework for industrial planning and design, validated against turbine and array flume tank and field data.
More information on the research background of the Energy group of the Engineering Department and recent and ongoing CFD-based research work is available at http://www.lancaster.ac.uk/engineering/research/energy/ and https://www.sites.google.com/site/mscampobasso/. The main academic research partner is the School of Engineering of Liverpool University, and the entire project will be carried out in close collaboration with Atlantis Resources Ltd. and EDF.
