class Inflow

Bases: BoundaryBaseWithTurbulenceQuantities

Inflow defines the inflow boundary condition based on the input spec.

Example

• Define inflow boundary condition with pressure:

  >>> fl.Inflow(
  ...     entities=[geometry["inflow"]],
  ...     total_temperature=300 * fl.u.K,
  ...     spec=fl.TotalPressure(1.028e6 * fl.u.Pa),
  ... )
  

• Define inflow boundary condition with mass flow rate:

  >>> fl.Inflow(
  ...     entities=[volume_mesh["fluid/inflow"]],
  ...     total_temperature=300 * fl.u.K,
  ...     spec=fl.MassFlowRate(123 * fl.u.lb / fl.u.s),
  ... )
  

• Define inflow boundary condition with turbulence quantities:

  >>> fl.Inflow(
  ...     entities=[volume_mesh["fluid/inflow"]],
  ...     turbulence_quantities= fl.TurbulenceQuantities(
  ...         turbulent_kinetic_energy=2.312e-3 * fl.u.m **2 / fl.u.s**2,
  ...         specific_dissipation_rate= 1020 / fl.u.s,
  ...     )
  ... )

name: str | None = 'Inflow'

Name of the Inflow boundary condition.

type: Literal['Inflow'] = 'Inflow'

total_temperature: Annotated[_AbsoluteTemperatureType, PlainSerializer(func=_dimensioned_type_serializer, return_type=PydanticUndefined, when_used=always), AfterValidator(func=_check_temperature_is_physical)] [Required]

Specify the total temperature at the Inflow boundary.

Constraints:

• func = <function _check_temperature_is_physical at 0x79c44aad76d0>

• return_type = PydanticUndefined

• when_used = always

velocity_direction: Axis | None = None

Direction of the incoming flow. Must be a unit vector pointing into the volume. If unspecified, the direction will be normal to the surface.

spec: TotalPressure | MassFlowRate [Required]

Specify the total pressure or the mass flow rate at the Inflow boundary.

turbulence_quantities: TurbulenceQuantitiesType | None = None

The turbulence related quantities definition.See TurbulenceQuantities() documentation.

entities: EntityList[Surface] [Required] (alias 'surfaces')

List of boundaries with boundary condition imposed.
