Influence of atmospheric gravity waves on wind turbine wake dynamics: A measurement-driven large-eddy simulation study

Abstract

We perform large-eddy simulation of wind turbine wake flow subjected to atmospheric gravity waves. The mesoscale forcing from atmospheric gravity waves is coupled to microscale turbine simulation using an indirect profile assimilation method. Our analysis will center on examining the effects of atmospheric gravity waves on wake meandering and wake-added turbulence, aiming to enhance understanding of the wake dynamics in the presence of atmospheric gravity waves. This study holds promise for guiding the development of wind farm models under realistic atmospheric conditions.
