This National Science Foundation (NSF) Engineering program (CFDA 47.041) award of $192,283 to Northeastern University supports collaborative research to model the influence of turbulence on flow-induced instabilities of large flexible structures, with a focus on wind turbine blades.

The research aims to develop a novel dynamic model for fluid-structure interaction (FSI) systems that accounts for the effects of turbulence on the onset and post-critical behavior of aeroelastic instabilities in asymmetric and highly flexible structures like wind turbine blades. Through a combination of experimental measurements and theoretical modeling, the project will produce models to more accurately characterize the aeroelastic loads on these types of structures under three-dimensional turbulent flow conditions. This research is expected to enable the development of longer and more efficient wind turbine blade designs by providing insights into instability thresholds and appropriate simulation approaches.
