LES of wake flow behind 2.3MW wind turbine AndersenSøren Juhl 2020 <h2><p>This database contains inflow and wake flow behind a 2.3MW turbine simulated using large eddy simulation(LES) in EllipSys3D. All three velocity components are given for downstream distances from 1R to 23R, where R = 46.5m. Please see </p><p>Liew, J., Urbán, A. M., and Andersen, S.
