Cette semaine à 13h45 en D001, Vincent Arnal, doctorant de l'équipe EMO fera une présentation sur :

"Experimental testing of model scale floating wind turbines : real-time hybrid numerical-physical methodology",

a collaborative work between EMO and Bassin teams.


Experimental testing of Floating wind turbines in a wave tank is still an essential stage for the validation of floater's design and for validation/calibration of hydrodynamic models.
While the Ocean Engineering wave tank of the LHEEA has a high-level quality wave generation system, up until now only a wind generating systems with large fans and a honeycomb could be used to reproduce the rotor response. This method has inherent issues.
Hybrid model testing of floating wind turbine is a promising alternative for correctly reproducing the rotor response.
In this approach, waves are still physically generated on a physical floating substructure while rotor response is emulated through a set of actuators coupled to a numerical simulator that computes in real time the aerodynamic loads.

During this mini-seminar, specifications for the actuators obtained from numerical simulations with OpenFAST will be presented, as well as the first test bench :  a 6 degrees of freedom hexapod reproduces at model scale pre-computed motions of a floating wind turbine while an aircraft turbine reproduces in real-time the aerodynamic forces.

The presentation will be followed by a demonstration of the first test bench.
