Abstract
Results of wingtip vortex surveys in the midfield wake of a flat-plate wing with AR=6 and a NACA 0015 wing with AR=5.35 are presented. The majority of the data was collected behind the flat-plate wing at Rec between 1.7 x 105 and 2.6 x 105. Previous comparisons of the experimental data with laminar and turbulent axisymmetric models suggested the trailing vortex had a consistent turbulent structure despite the moderate vortex-circulation Reynolds number. Current comparisons with the turbulent n-family of vortices indicate a high level of turbulence in the vortex. Surveys behind the NACA 0015 wing also suggest a turbulent profile, but indicate a lower level of turbulence despite a higher vortex-circulation Reynolds number. © 2023, American Institute of Aeronautics and Astronautics Inc, AIAA.
