The seminars are an opportunity for exchange between PhD students and staff, as well as between the different teams of LHEEA, and take place in the following way:

This week:

Antoine SOULIER (DAUC) will present her work on "Penon Electronique, un capteur pour détecter le décollement sur les pâles d’éoliennes. "

" Wind turbine’s inflow conditions are highly unsteady and inhomogeneous due to, for instance, atmospheric turbulence, wind shear, blade rotation in front of the mast, and rotor misalignment (yaw). These perturbations contribute to increase fatigue loads which limit the wind turbine's life-time and decrease the energy extraction. Most of the sensors are located on the nacelle, but nothing exists to monitor the flow on the blades. The sensor used in the present study, electronic TellTale, is designed to detect the flow separation through an electronic device mounted on the aerodynamic surface with an embedded strain gauge on which a silicone tail is attached.
This device can be easily mounted on a real blade. Wind tunnel tests were performed in the NSA wind tunnel in the CSTB with an e-TellTale mounted on a NACA 654-421 airfoil. These experimentations were used to test the airfoil in order to improve it for the next tests, to show the low influence of the e-Telltale on some of the aerodynamic values and to investigate the ability of the sensor to detect boundary layer separation."
