ActuatorDisk

class ActuatorDisk

Bases: Flow360BaseModel

ActuatorDisk class for setting up the inputs for an Actuator Disk. Please refer to the actuator disk knowledge base for further information.

Note

Cylinder.center, Cylinder.axis and Cylinder.height are taken as the center, thrust axis, and thickness of the Actuator Disk, respectively. The radius of the Actuator Disk is the last value of ForcePerArea.radius. Mesh nodes closer to the axis than Cylinder.inner_radius receive no actuator disk force, so a non-zero inner radius leaves a central region, such as a hub, unloaded.

Example

>>> fl.ActuatorDisk(
...     entities = fl.Cylinder(
...         name="actuator_disk",
...         center=(0,0,0)*fl.u.mm,
...         axis=(-1,0,0),
...         height = 30 * fl.u.mm,
...         outer_radius=5.0 * fl.u.mm,
...     ),
...     force_per_area = fl.ForcePerArea(
...          radius=[0, 1] * fl.u.mm,
...          thrust=[4.1, 5.5] * fl.u.Pa,
...          circumferential=[4.1, 5.5] * fl.u.Pa,
...     )
... )

Attributes

entities: EntityList[Cylinder]

The list of Cylinder entities for the ActuatorDisk model

force_per_area: ForcePerArea

The force per area input for the ActuatorDisk model. See ForcePerArea documentation.

reference_velocity: Velocity.Vector3, optional

Reference velocity [Vx, Vy, Vz] for power calculation. When provided, uses this velocity instead of local flow velocity for the actuator disk power output.

Default:

None

name: str, optional

Name of the ActuatorDisk model.

Default:

'Actuator disk'
