Industrial Wake Models

This chapter deals with the description of wind turbine wakes by means of reduced-complexity flow models. These models offer the appeal to conduct a vast number of simulations of the wake flow for different atmospheric boundary conditions in short time, thus, they are usually the models of choice in the wind energy industry for assessing and optimizing long-term energy production. The intent of the chapter is to provide an overview over a subset of the most prominent wake models, their physical approximations, and the resulting equations that the models use to describe the flow. At the end, two algorithms are presented to derive a converged wind farm flow by superimposing the wake deficits derived from the presented single wake models. This offers the readers the opportunity to implement a wind farm flow model with their wake model of choice themselves.
