class foxes.models.wake_deflections.JimenezDeflection(foxes.core.WakeDeflection)[source]

Yawed rotor wake defection according to the Jimenez model

Attributes

rotate: bool

If True, rotate local wind vector at evaluation points. If False, multiply wind speed with cos(angle) instead. If None, do not modify the wind vector, only the path.

beta: float

The beta coefficient of the Jimenez model

step_x: float

The x step in m for integration

Public members

JimenezDeflection(rotate=True, beta=0.1, step_x=10.0)[source]

Constructor.

__repr__()[source]

Return repr(self).

property has_uv

This model uses wind vector data

calc_deflection(algo, mdata, fdata, tdata, downwind_index, coos)[source]

Calculates the wake deflection.

get_yaw_alpha_seq(algo, mdata, fdata, tdata, downwind_index, x)[source]

Computes sequential wind vector rotation angles.

classmethod new(wframe_type, *args, **kwargs)[source]

Run-time wake deflection model factory.

property model_id

Unique id based on the model type.

var(v)[source]

Creates a model specific variable name.

property initialized

Initialization flag.

sub_models()[source]

List of all sub-models

load_data(algo, verbosity=0)[source]

Load and/or create all model data that is subject to chunking.

initialize(algo, verbosity=0, force=False)[source]

Initializes the model.

property running

Flag for currently running models

set_running(algo, data_stash, sel=None, isel=None, verbosity=0)[source]

Sets this model status to running, and moves all large data to stash.

unset_running(algo, data_stash, sel=None, isel=None, verbosity=0)[source]

Sets this model status to not running, recovering large data from stash

finalize(algo, verbosity=0)[source]

Finalizes the model.

get_data(variable, target, lookup='smfp', mdata=None, ...)[source]

Getter for a data entry in the model object or provided data sources
