报告摘要：The aim of the present examination is to obtain a betterunderstanding of the wake formations and interactions between wind turbines inwind farms. Two main differences in the wake behavior for the disk-disk and therotor-rotor systems were found: the wake intensity grows for the dual disks incomparison with the single one, but in contrast to this, wake intensity behindthe dual rotor system is smaller than the one behind a single rotor. Thesedifferences may be explained by an influence of the rotor tip vortices whichare absent in the disk-disk model. The present retesting of the near and farwake data should provide an evidence of this conclusion.
