Abstract

Many sites where tidal energy may be exploited can be modelled as a strait between an island and a semi-infinite landmass. The presence of the island constrains the flow and induces a local acceleration in the current that yields high energy densities in the strait. This presentation will describe a preliminary study that is on-going into the influence of the strait and island geometry and the seabed friction on tidal power extraction from the strait. The length of the strait, width of the island, and seabed drag are anticipated to have a positive correlation with the ratio of maximum dissipated power to the undisturbed kinetic energy flux in the strait.
