Wake Parametrization and surrogate modelling for loads prediction
Résumé
ln a wind farm, the wind velocity field hitting a rotor has some specificities.
lndeed, when a wind turbine (WT) is located inside a warm, it experiences a
modified wind field compared to the ambient one. Typically, inside a wake, the
wind exhibits a reduced mean velocity and an increased turbulence intensity.
The current design approach for wake induced load analysis just consists in
using a kind of equivalent turbulence intensity that would cause the same
damage as the wake induced wind field [1]. But this simplified approach does
not account for the specific shape of the wake velocity field and may lead to
inappropriate (conservative or under-conservative) load predictions especially
for rotors operating in partial-wake conditions.
