Abstract
The presence of a region of multi-modal velocity histograms in the plane of symmetry of a wing-body juncture have been reported. This region not only contains bi-modal histograms but also tri-modal distributions. LDV measurements supplemented by detailed analysis of the flow-visualization results has been used to propose that the reason for this behavior is the dynamic character of the juncture-vortex system and not turbulent intermittency as reported earlier.
