Computes sequential wind vector rotation angles.

Wind vector rotation angles are computed at the current trace points due to a yawed rotor for sequential runs.

Parameters¶

algo: foxes.core.Algorithm

The calculation algorithm

mdata: foxes.core.MData

The model data

fdata: foxes.core.FData

The farm data

tdata: foxes.core.TData

The target point data

downwind_index: int

The index of the wake causing turbine in the downwind order

x: numpy.ndarray

The distance from the wake causing rotor for the first n_times subsequent time steps, shape: (n_times,)

Returns¶

alpha: numpy.ndarray

The delta WD result at the x locations, shape: (n_times,)
