Characterization of atmospheric coherent structures and their impact on a utility-scale wind turbine
Aliza Abraham, Jiarong Hong
Atmospheric turbulent velocity fluctuations are known to increase wind turbine structural loading and accelerate wake recovery, but the impact of vortical coherent structures in th…
Evidence of preferential sweeping during snow settling in atmospheric turbulence
Jiaqi Li, Aliza Abraham, Michele Guala +1
We present a field study of snow settling dynamics based on simultaneous measurements of the atmospheric flow field and snow particle trajectories. Specifically, a super-large-scal…
Settling and Clustering of Snow Particles in Atmospheric Turbulence
Cheng Li, Kaeul Lim, Tim Berk +5
The effect of turbulence on snow precipitation is not incorporated into present weather forecasting models. Here we show evidence that turbulence is in fact a key influence on both…
Operational-dependent wind turbine wake impact on surface momentum flux revealed by snow-powered flow imaging
Aliza Abraham, Jiarong Hong
As wind energy continues to expand, increased interaction between wind farms and their surroundings can be expected. Using natural snowfall to visualize the air flow in the wake of…
Effects of Inflow Turbulence on Structural Deformation of Wind Turbine Blades
Linyue Gao, Shu Yang, Aliza Abraham +1
The present investigation provides the first field characterization of the influence of turbulent inflow on the blade structural response of a utility-scale wind turbine (2.5MW), u…
Snow-powered Research on Utility-scale Wind Turbine Flows
Jiarong Hong, Aliza Abraham
This paper provides a review of the general experimental methodology of snow-powered flow visualization and super-large-scale particle imaging velocimetry (SLPIV), the correspondin…
