Effects of ambient turbulence and stratification on the demise of trailing vortices
A technical report from the Naval Postgraduate School in Monterey, California, by Turgut Sarpkaya and John J. Daly, on how ambient turbulence and stratification cause trailing vortices to decay. The pictures are plain contour plots of vortex fields over axes labelled X/B0 and a vertical coordinate, with dashed and solid lines marking levels, plus one scatter chart of dimensionless height against time, so a designer can take their sparse line-and-grid vocabulary as a model for data graphics.
