Model

FarmFlow

FarmFlow is an ECN wake model. It is a simplified CFD solver, i.e., based on 10 minute-averaged parabolized Navier–Stokes equations. It furthermore uses a K-ε turbulence model. The input turbulence intensity is also used to estimate wind shear. It assumes twelve 30° wind directions and outputs speeds with a resolution of 1 m/s. Usually, rotor-averaged wind speed at hub height is output, but arbitrary cell wind speeds can be requested.
