The Bolund Experiment

The Bolund experiment provides a new dataset for validating flow models in complex terrain.

WindSim proudly particpated in the Bolund experiment, a new validation case undertaken by Risø, and congratulates our fellow contributors.

The CFD methods—including WindSim—showed the lowest errors among the various methods used.

The Bolund experiment is a field campaign that provides a new dataset for validating numerical models of flow in complex terrain and is the basis for a unique blind comparison of flow models.

Today, many flow models are evaluated against hill experiments of simple geometry often performed at laboratory scales in wind tunnels. However, in order to validate the models, full scale field experiments with realistic terrain forms are necessary.

The Bolund experiment allows such a validation.
