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…
