The benchmark is open to participants of the Wakebench project using flow models over topography in neutral conditions. The study will show the changes in the mean flow field above the Askervein hill for different incident flow angles defined by the following wind directions:

  • 210º, perpendicular to the long axis of the hill (classical reference),
  • 130º, parallel to the long axis, and
  • 90º, in the wake of upstream hills.


Test model fine-tuning strategies that will be applied in complex terrain sites. Evaluate turbulence models in a test site with reasonably well defined boundary conditions. Evaluate the ability of the models to predict wind direction variations close to the ground induced by local topography.

Data Accessibility

The benchmark is offered to participants of the IEA Task 31 Wakebench.
