This thesis examines the impact that turbulence and turbine operating condition have on the wake of a horizontal axis tidal turbine, and the implications of this impact for array design. This is done via the use of computer simulations using a scale-

A physics-based actuator disk model (PBADM) was derived using blade-resolved turbine LES wake data for a blade/hub configuration and was incorporated into a RANS implementation in OpenFOAM. The PBADM attempts to address the limitations of the current

National efforts to reduce energy dependency on fossil fuels have prompted examination of macrotidal nearshore sites around the United Kingdom (UK) for potential tidal stream resource development. A number of prospective tidal energy sites have been

With tidal turbine technology in its infancy prototype devices are likely to be positioned at locations where both the local marine environment and vessel navigation are favourable. However, as marine turbine technology develops toward economic viabi

The impact of local depth-wise velocity profiles on tidal turbine performance is important. Although the use of standard power laws for predicting velocity profiles is common, these laws may underestimate the magnitude of the depth-wise velocity shea

The renewable energy route map for Wales outlines ambitious targets for 50% renewables by 2025. The Welsh coast, subject to tidal ranges of the order of 13 m and tidal flows in excess of 3 m/s, is thus in an ideal position to significantly contribute
