Video: Swirling snowflakes reveal wind turbine airflow
Let it snow, let it flow – that’s how researchers visualised for the first time how full-sized wind turbines interact with the surrounding air.
Jiarong Hong and his team from the University of Minnesota took advantage of some cold Minneapolis weather to research late-night snowstorms. They shone powerful searchlights through thick blankets of snowflakes to reveal large-scale turbulent flow structures that can’t be replicated in small-scale lab experiments.

A better understanding of this flow could make turbines more efficient and reliable.
