Stretching Behavior of Knotted and Unknotted Flow Fields
Stefan Faaland, Diego Tapia Silva, Dustin Kleckner
Vortex stretching is a common feature of many complex flows, including turbulence. Experiments and simulations of isolated vortex knots demonstrate that this behavior can also be s…
Retention of rising droplets in density stratification
Tracy Mandel, De Zhen Zhou, Lindsay Waldrop +3
In this study, we present results from experiments on the retention of single oil droplets rising through a two-layer density stratification. These experiments confirm the signific…
How superfluid vortex knots untie
Dustin Kleckner, Louis H. Kauffman, William T. M. Irvine
Knotted and tangled structures frequently appear in physical fields, but so do mechanisms for untying them. To understand how this untying works, we simulate the behavior of 1,458…
Helicity conservation by flow across scales in reconnecting vortex links and knots
Martin W. Scheeler, Dustin Kleckner, Davide Proment +2
The conjecture that helicity (or knottedness) is a fundamental conserved quantity has a rich history in fluid mechanics, but the nature of this conservation in the presence of diss…
The Life of a Vortex Knot
Dustin Kleckner, Martin Scheeler, William T. M. Irvine
The idea that the knottedness (hydrodynamic Helicity) of a fluid flow is conserved has a long history in fluid mechanics. The quintessential example of a knotted flow is a knotted…
