||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.
Few experimental scale tests have been conducted to assess the performance of one tidal turbine. However, there is a growing need for scale testing in order to validate numerical models which will predict the effect of the ambient flow conditions on the power performance and the wake shape and intensity of a tidal turbine. The intention of WG4 WP3 is to obtain experimental data describing the wake and performance of ducted device concepts. This document provides an explanation of the test procedure, the format of the collated data and the quality control processes employed during the experiments.
