SlaterPorousBleed

class SlaterPorousBleed

Bases: Flow360BaseModel

SlaterPorousBleed is a no-slip wall model which prescribes a normal velocity at the surface as a function of the surface pressure and density according to the model of John Slater.

Example

• Specify a static pressure of 1.01e6 Pascals at the slater bleed boundary, and set the porosity of the surface to 0.4 (40%).

>>> fl.SlaterPorousBleed(static_pressure=1.01e6 * fl.u.Pa, porosity=0.4, activation_step=200)

---

Attributes

static_pressure: PressureType.Positive

The static pressure value.

porosity: float

The porosity of the bleed region.

activation_step: int, optional

Pseudo step at which to start applying the SlaterPorousBleedModel.

Default:

None

Additional Constructors

classmethod from_file(filename)

Loads a Flow360BaseModel from .json, or .yaml file.

Parameters:

filename (str) – Full path to the .yaml or .json file to load the Flow360BaseModel from.

Returns:

An instance of the component class calling load.

Return type:

Flow360BaseModel

Example

>>> params = Flow360BaseModel.from_file(filename='folder/sim.json') 

Methods

help(methods=False)

Prints message describing the fields and methods of a Flow360BaseModel.

Parameters:

methods (bool = False) – Whether to also print out information about object’s methods.

Return type:

None

Example

>>> params.help(methods=True) 

to_file(filename, **kwargs)

Exports Flow360BaseModel instance to .json or .yaml file

Parameters:

filename (str) – Full path to the .json or .yaml or file to save the Flow360BaseModel to.

Return type:

None

Example

>>> params.to_file(filename='folder/flow360.json')
