Hostile Takeover of Small Fluid Vortices
New experiments and simulations show that large-scale fluid circulations drain
energy from smaller-scale vortices to sustain themselves, akin to a hostile takeover
of smaller corporations. The figure shows a visualized flow from a laboratory
experiment of a thin salt-water layer driven by magnetic forces.
One can see vortex structures on a range of scales.
