Model parameters and implementation notes

The windIO inputs and their software-specific mappings are listed below. Matching literature-model names do not imply identical solver, rotor-averaging, superposition, turbulence, induction, or yaw treatments.

windIO case inputs

velocity: bastankhah2016alpha = 0.58, beta = 0.077, ka = 0.3837, kb = 0.003678

FLORIS

velocity: gaussalpha = 0.58, beta = 0.077, ka = 0.3837, kb = 0.003678

Uses sum-of-squares freestream deficit superposition (sosfs), a nine-point turbine-grid solver, and Crespo-Hernandez wake-added turbulence. Secondary steering, yaw-added recovery, transverse velocities, and active wake mixing are disabled.

FOXES

velocity: Bastankhah2016alpha = 0.58, beta = 0.077, kTI = 0.3837, kb = 0.003678, induction = Betz, k = from kTI turbine model

Uses Betz induction, quadratic wind-speed superposition, grid16 rotor sampling, rotor-point partial wakes, and the rotor_wd wake frame. No separate wake-added turbulence model is configured.

The ka and kb inputs configure a separate kTI turbine model; the wake model receives k=None so expansion is supplied by that turbine model.
