Turbulence is all around us. It's in the swirl of coffee and milk in a latte, unfurling along the wings of airplanes and the sides of cars, churning the blood in your heart after the valve snaps closed. Yet we still don't fully grasp all of its rules.
Thank you! If I am understanding right, I think my guess was pretty bang on. Fig. 3b shows the energy dissipation from the center of the vortex blob moving outward and shows a steep drop off past where they define their edge (brown line).
Also, thank you so much for the extension recommendation! I have journal access through work for journals I go to frequently, so I forget about arxiv sometimes.
