Effects of wind veer on a yawed wind turbine wake in atmospheric boundary layer flow
Ghanesh Narasimhan, Dennice F. Gayme, Charles Meneveau
Abstract
Large Eddy Simulation (LES) is used to study the wind veer effects on the wake of a yawed wind turbine. The veer deflects the wake in the spanwise direction, and this effect can be captured in the wake model by adding a veer correction term. The counter-rotating vortex pair structures previously observed behind yawed turbines can also be recovered by subtracting the background veer vorticity.
