How turbulence plays out in exotic materials
By Marissa Cevallos, 11:03 AM February 24, 2011
Grab a mug and slosh the morning coffee around and around and a spinning vortex appears. The swirling rings, with their eddies and choppy waves, obey the laws of classical turbulence, which engineers and applied physicists routinely invoke to study how air flows over an airplane wing or how blood flows through tiny vessels.
Shake up a cup of quantum fluid instead and you still get vortices, but nothing like the tornado in your morning brew.
Quantum vortices can look like tiny rings that ...
