Rotor-Averaging Methods

class MITWake.REWS.Area(r_disc=10, theta_disc=10)

grid_points(X_t: ndarray, Y_t: ndarray) → Tuple[ndarray, ndarray, ndarray]

Returns the grid points to be sampled given the turbine locations, X_t, Y_t

Parameters:

• X_t (List[float]) – Streamwise locations of turbines.

• Y_t (List[float]) – Lateral locations of turbines.

Returns:

X, Y, Z coordinates of grid points.

Return type:

(ndarray, ndarray, ndarray)

integrate(U: ndarray) → ndarray

Numerically integrate wind speeds sampled at grid point locations defined by Point.grid_points.

Parameters:

U (np.ndarray) – Streamwise wind speeds.

Returns:

Array of Rotor-averaged wind speeds for each rotor.

Return type:

np.ndarray
