Short summary
We studied the airflow around a new type of wind turbine called the X-Rotor, which could help to reduce the cost of offshore wind energy. Comparing a computer simulation model and wind tunnel experiments, we found that the model correlates well under normal conditions but becomes less accurate when the blades pitch. Our results show that future designs of this turbine category must consider complex 3D flow effects to better predict and improve wind turbine performance.
