|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.
This report forms part of work package WG3WP2, the objective of which is to:
- model the interaction of three dimensional unsteady flow and turbine wakes within an array;
- verify available numerical models; and
- implement an appropriate free surface model within Code_Saturne.
This report provides the reader with an introduction, methodology and guide to implementation of the work conducted to provide a suitable means of tidal stream modelling. The tidal stream modelling is seen as an important component to the whole project since it provides the necessary upstream boundary condition to a small array of marine current turbines at the meso-scale using EDF’s Computational Fluid Dynamic (CFD) solver ‘Code_Saturne’
