FlowObstruction

https://bladednextgen.dnv.com/schema/0.4.1/Components/Tower/TowerAerodynamicProperties/FlowObstruction/FlowObstruction.json

The properties of the tower shadow, which modifies the flow in the region around the tower. This has a direct affect on the flow as the blade sees it.

  • PotentialFlow: object (TowerShadowPotentialFlow)
  • Powles: object (TowerShadowPowles)

Properties

PotentialFlow: object(TowerShadowPotentialFlow), optional

Parameters for the potential flow tower shadow model. This can be defined in addition to the Powles model to form a combined tower shadow model, where the potential flow model is used upwind of the tower, and the two flow fields are combined downwind.

Powles: object(TowerShadowPowles), optional

Parameters for the empirical Powles tower shadow model. This can be defined in addition to the potential flow model to form a combined tower shadow model, where the potential flow model is used upwind of the tower, and the two flow fields are combined downwind.
