Popis: We present a wind tunnel study of a model wind turbine wake with regard to different inflow conditions. The aim is to examine the influence of intermittent flows on the wake. For this, a regular grid that produces non-intermittent inflow and an active grid that creates intermittent inflows have been used. As a reference case, also laminar inflow conditions were examined. The development of the centerline turbulence intensity and mean velocity with increasing distance from the wind turbine was investigated, and an influence of the different characteristic features of turbulence on the wake recovery was found. The results expand and partially contradict previous results.
