Abstract

The present research project proposes the development of a computational wind turbine aeroelastic model where the aerodynamic model accounts for the nonlinear effects of flow separation and dynamic stall. By doing so, this work complements the development of an aeroelastic model in the original process (FAPESP process 2014/21166-7 - scientific initiation grant), where unsteady vortex lattice method (UVLM) is used. Modifications to the UVLM are planned in order to correct the predicted potential loads to nonlinear behavior associated to flow separation and stall.
