A Comprehensive Review on Analytical Formulations of Wind Turbine Wake Models and Future Scope in the Development of Wind Farms of Assorted Configurations

Abstract

Of late, the design and development of large and small wind farms are gaining importance to meet the growing energy demand. In this aspect, several wind turbine wake models have been proposed over the years, some of which are the legacy of Jensen, Larsen, Lissaman, Frandsen, and Ainslie wake models. Despite their robustness, the analytical formulations of these models are widely explored as research tools for estimating the performance of wind farms. However, because of several limitations and assumptions like top-hat shape, Gaussian profile, axisymmetric, negligible atmospheric boundary layer effect, and others, these models often overestimate the flow characteristics. In view of this, there is always a scope for developing better correlations to predict the performance of wind farms more accurately. This article gives a conspectus of various wind turbine wake models that have evolved over the years and then recommends some conceptual wind farm designs of assorted configurations.
