Wind turbine single and multiple wake effects

  The layout of wind turbines with respect to the prevailing wind direction is a major subject of the current research efforts aiming to minimize the wake interactions or “wake effects” of wind turbines that can be installed in a specific area and finally to maximize the efficiency of the wind farm. The term “wake effects” is used to describe the generation and development of the wake downstream of a wind turbine as well as the wake interactions within a wind farm.

  The kernel part of a method to optimize the layout of the turbines of a wind farm is a wake model. Wake modeling of wind turbines has attracted a lot of attention by the research community during the past decade especially for very large offshore wind farm installations where wake effects are responsible for quite a significant percentage of power output losses. Although a number of analytical and semi-empirical simple models have been developed for wake modeling, they are not capable of providing satisfactory predictions for different turbulence conditions. The substantial progress in computer resources has permitted cost efficient calculations using more sophisticated methods such as the solution of Navier-Stokes equations.
