 ERF supports models for wind farm parametrization in which the effects of wind turbines are represented by imposing a momentum sink on the mean flow and/or turbulent kinetic energy (TKE). Currently the Fitch model (`Fitch et al. 2012`_), Explicit Wake Parametrization (EWP) model (`Volker et al. 2015`_), Simplified actuator disk model (See Section 3.2 in `Wind Energy Handbook 2nd edition`_), and Generalized actuator disk model (`Mirocha et. al. 2014`_, see Chapter 3 of `Small Wind Turbines`_) are supported.
