Analytical Descriptions of Swirling Wake Profiles

Abstract Wake behavior significantly affects the performance and lifetime of wind turbines on which it impacts. This study considers wake profile fits applied to velocity data gathered in a swirling turbulent wake. rotation or swirl has been found impact growth evolution, thus both deficit profiles are fit. Specifically, Gaussian double functions profiles, Lamb-Oseen Taylor distributions used for tangential profiles. Fits that accurately represent promise improve representations can be used, example, stability theory analyses modeling. The vortex were best distributions, but distribution failed capture true at some radial locations. An example use these quantify evolution is provided.
