Electricity production from wind energy has grown at a fast pace over the last few years. The size of individual
wind turbines has also increased significantly and it is unclear if this trend can b sustained in the future for
structural reasons, especially regarding rotor blade components. A research programme is being undertaken to
investigate these issues, and finite element modelling will be extensively used to examine the static and
dynamic limitations of wind turbine blades. As an initial step in this research, a flexible full blade model was
created and is presented in this
paper. The wind energy technical community has begun to seriously consider the potential of aerodynamic
control methodologies for mitigating adverse aerodynamic loading. Spatial and temporal attributes of the
structures and processes present in these flow fields hold important implications for active aerodynamic control
methodologies currently being contemplated for wind turbine applications. The current work uses
complementary experimental and computational methodologies, to isolate and characterize key attributes of
blade flow fields associated with axisymmetric and yawed turbine operation. During axisymmetric operation, a
highly three-dimensional, shear layer dominated flow field yields rotational augmentation of both mean and
standard deviation levels of aerodynamic forces.
