umerical simulation of atmospheric boundary layer and wakes of horizontal-axis wind turbines
Journal of Energy in Southern Africa, 2017 Simulations of wind turbine wakes are presented in this paper using the three-dimensional Reynolds-Averaged Navier-Stokes (RANS) equations employing the k-e turbulence model appropriately modified for the atmospheric flows.

Characterization of wind turbine wakes in a non-sheared turbulent flow [Elektronisk resurs] [PDF]
, 2013 The characteristics of the turbulence field in wakes produced by horizontal-axis wind turbines under a uniform inflow are studied. To this aim, LES simulations of a rotor subjected to different types of inflow are performed with OpenFOAM.
