Parameters:
function(x_i, y_i, yaw_i, turbulence_intensity_i, ct_i, rotor_diameter_i, *, x)[source]#

Calculates the deflection field of the wake in relation to the yaw of the turbine. This is coded as defined in [1].

Args:

x_locations (np.array): streamwise locations in wake y_locations (np.array): spanwise locations in wake z_locations (np.array): vertical locations in wake

(not used in Jiménez)

turbine (floris.core.turbine.Turbine):

Turbine object

coord

(floris.core.turbine_map.TurbineMap.coords()): Spatial coordinates of wind turbine.

flow_field

(floris.core.flow_field.FlowField): Flow field object.

Returns:

deflection (np.array): Deflected wake centerline.

This function calculates the deflection of the entire flow field given the yaw angle and Ct of the current turbine

  • x_i (ndarray)

  • y_i (ndarray)

  • yaw_i (ndarray)

  • turbulence_intensity_i (ndarray)

  • ct_i (ndarray)
