Dynamics and Transport within Delta Wing Leading-Edge Vortices

Three-dimensional Particle-Tracking Velocimetry measurements were obtained on a non-slender delta wing with leading-edge sweep angle of 50 degrees and sharp leading edges in order to examine the dynamics and transport processes within the leading-edge vortices. Experiments were conducted in a wind-tunnel at Reynolds numbers on the order of 10^5, and analyzed through the scope of a vorticity transport framework. Data-driven analysis techniques are also employed to subsets of the flow to examine the dynamics of dominant structures in the flow and gain further insights into the transport mechanisms.
