||The Performance Assessment of Wave and Tidal Array Systems (PerAWaT) project, launched in October 2009 with £8m of ETI investment. The project delivered validated, commercial software tools capable of significantly reducing the levels of uncertainty associated with predicting the energy yield of major wave and tidal stream energy arrays. It also produced information that will help reduce commercial risk of future large scale wave and tidal array developments.
WG3 WP6 D5 aims to present the methodology used to describe the fundamental device concept (FDC) tidal arrays in numerical models created for the M2 tidal constituent.
- The report first introduces the two-dimensional Shallow Water Equations (SWEs) and the chosen numerical method (discontinuous Galerkin finite element method) used to solve these equations.
- The methodology is then explained for couplingLinear Momentum Actuator Disc Theory (LMADT) to the two-dimensional hydrodynamic model DG-ADCIRC by means of including a line sink of momentum within the discontinuous Galerkin scheme.
- The verification of the algorithm is undertaken for a number of problems where an array of tidal devices is located in an idealised channel, with different configurations and problem settings.
- Lastly, preliminary results are given for the Anglesey Skerries, using the modified DGADCIRC code that uses LMADT tocalculate the relevant line sink of momentum in the solution domain
