Turbine Models

class MITWake.Turbine.BasicTurbine(Ct: float, yaw: float, x=0.0, y=0.0, sigma=0.25, kw=0.07, induction_eps=1e-06)

deficit(x: ndarray, y: ndarray, z=0, FOR: Literal['met', 'local'] = 'met') → ndarray

Returns the wake deficit generated by the turbine sampled at the given positions in space.

Parameters:

• x (np.ndarray) – Longitudinal positions to sample.

• y (np.ndarray) – Lateral positions to sample.

• z (int) – Vertical positions to sample. Defaults to 0.

• FOR (Literal["met", "local"]) – Frame of reference. Defaults to

• the (freestream velocity is along the x axis. "local" indicates) –

• the –

• where (turbine frame of reference) –

• turbine. –

Returns:

Wake deficit at sample points.

Return type:

np.ndarray
