Modelling tidal energy extraction in a depth-averaged coastal domain

, 2010
An extension of actuator disc theory is used to describe the properties of a tidal energy device, or row of tidal energy devices, within a depth-averaged numerical model This approach allows a direct link to be made between an actual tidal device and its

Tidal turbine array modelling

, 2014
Computational fluid dynamics (CFD) is used in this thesis to model wind and tidal stream turbines and to investigate tidal turbine fence performance. There are two primary objectives of this work. The first is to develop and validate an actuator line method for the simulation of wind and tidal turbines which applies the blade forces to the flow field ...

A method for analysing fluid structure interactions on a horizontal axis tidal turbine

, 2011
Free stream tidal turbines are rotating bodies in fast flowing tidal currents, and as such are exposed to fluctuating loads from the surrounding fluid.

Optimal design of a tidal turbine

IOP Conference Series: Earth and Environmental Science, 2012
An optimal design procedure has been applied to improve the design of an open-center tidal turbine. A specific software developed in C++ enables to generate the geometry adapted to the specific constraints imposed to this machine. Automatic scripts based on the AUTOGRID, IGG, FINE/TURBO and CFView software of the NUMECA CFD suite are used to evaluate ...

Development of high performance composite bend-twist coupled blades for a horizontal axis tidal turbine

, 2009
Development of a design methodology for a composite, bend-twist coupled, tidal turbine blade has been undertaken. Numerical modelling was used to predict the response of the main structural member for the adaptive blade.
