In this area, the wind is turbulent and gusty, generating unsteady aerodynamic forces that cause premature structural damage and reduced performance. A better understanding of unsteady turbulent flows over aerofoils would help to improve the estimation of the dynamic forces.
The MISTERY project involves an interdisciplinary team of researchers in aerodynamics, machine learning and electronics, from ETHZ and OST in Switzerland, and CentraleSupélec and Centrale Nantes in France. The team investigates the impact of turbulence on aerodynamic performance of wind turbine blades. To achieve this, we study the aerodynamics of a 1:1 scale of a section of a wind turbine blade in a large wind tunnel (4m x 5m with wind speeds up to 50m/s) in Nantes (figure 1). The blade is instrumented with over 300 pressure sensors and the flow is visualised with PIV. These measurements will create a large open database that will be used to develop models for flow control of for structural health monitoring.
