MaRINET2 Fatigue Loading from Unsteady Flow Features (FLUFF)

Project: EU Commission

Project Details


Turbulence- and wave-induced forces on tidal turbine blades reduce the reliability and longevity of devices. The applicants have shown that a crucial flaw in present modelling methods is the assumption of locally 2D flow, and that using a 3D model significantly improves the accuracy of unsteady force prediction. We also showed that by accounting for 3D effects it is possible to modulate turbine load response to unsteady flow using static turbine design (see attached document for overview). In this project, we will test two sets of turbine blades; one designed to have reduced load response to marine turbulence, and one designed to have large response. A performance comparison when operating in turbulence and waves will demonstrate the new design method for reducing unsteady loads

Layman's description

Tidal turbines could provide 20% of the UK's electricity, but costs and reliability are preventing widespread deployment. The sea is a notoriously harsh environment, with highly unsteady flow from waves and other eddies. This project will enable the design of tidal turbines that are better able to survive in this environment and thus lower costs and increase reliability.
