Tidal Stream Energy Extraction in Coastal Basins

Tidal Stream Energy Extraction in Coastal Basins A thesis submitted for the degree of Doctor of Philosophy Scott Draper St Catherine's College, Oxford Trinity Term 2011 In recent years the extraction of energy from tidal streams has grown in popularity as a potential source of clean renewable energy. To extract this energy, tidal devices, resembling underwater turbines or hydroplanes, are deplo...

Characteristics of the turbulence in the flow at a tidal stream power site.

This paper analyses a set of velocity time histories which were obtained at a fixed point in the bottom boundary layer of a tidal stream, 5 m from the seabed, and where the mean flow reached 2.5 m s(-1). Considering two complete tidal cycles near spring tide, the streamwise turbulence intensity during non-slack flow was found to be approximately 12-13%, varying slightly between flood and ebb ti...

The Influence of Solidity on the Performance Characteristics of a Tidal Stream Turbine

The performance characteristics of a tidal stream turbine are critical when assessing its economical viability. The solidity of the rotor, which is a function of the blade chord length and the number of blades, will affect the performance characteristics, from both a power output and a structural
