||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 details calibration of the experimental flow conditions, rotor and electro-mechanical systems for the equipment described in WG4 WP2 D2. Measurements are presented of the flow structure, of the characteristic of the small-scale rotor and of the structure of the wake of a single turbine and pair of turbines. The information presented demonstrates that the planned turbine tests can be calibrated correctly.
