Measurements in the near-field of a turbulent wingtip vortexThe roll-up of a wingtip vortex, at Reynold's number based on chord of 4.6 million, was examined with emphasis on suction side and near wake measurements. Surface oil flow and laser smoke flow studies are performed, demonstrating the highly 3D nature of the flow around the wingtip, the formation of the feeding sheet, and the viscous core region of the vortex. Flow visualization and correlation measurements show that meandering of the vortex is small and does not appreciably contribute to the turbulence measurements.
