Onset and Prediction of Orbital Motions of Streamwise Vortices

Abstract

This research program investigates theoretically the evolution and stability of trailing vortices and their interactions with solid surfaces or flexible wings. Several analytical and numerical approaches are applied across five model scenarios with different vortex structures and configurations with respect to a planar surface and/or an aeroelastic lifting body. A nonmodal, temporal stability analysis of a three dimensional trailing vortex pair approaching an inviscid ground plane indicates that the suppression of the dominant Crow instability near the ground plane can be described with inviscid fluid dynamics and does not require an appeal to dissipative viscous flow effects.
