Context
In order to optimize the operation of MRE systems (wind turbines, tidal turbines, etc.), it is essential to move towards a more detailed characterization of the aerodynamic or hydrodynamic loads imposed by the environment in which they operate.
It is in this context that the TRPIV4EMR project, winner of the WEAMEC Small Equipment call for projects in 2021, aims to acquire a time-resolved Particle Image Velocimetry (PIV) system for the LHEEA laboratory’s MRE applications.
Scientific breakthroughs and innovation
Unlike conventional PIV, this rapid PIV method makes it possible to capture the rapid turbulence dynamics of incident wind or in the wake of wind turbines. This measurement method is the only experimental technique in the laboratory capable of acquiring a spatio-temporal description of the multi-scale aerodynamic or hydrodynamic flows found in wind, wave, or tidal energy recovery systems.
Expected technical and economic impact
The equipment acquired would enable more detailed characterization of the aerodynamic or hydrodynamic loads imposed by the environment on MRE systems, particularly with regard to unsteady loads, which cause additional fatigue on structures.
Precise measurement of unsteady flow near the structure could provide unique information.
