Quickly after vortex lines snap away from each other, they could jerk and wiggle and form what are called "Kelvin waves.
Recent theory suggests the decay occurs through a Kelvin-wave cascade on the vortex lines which couples the initially large turbulent eddies to the short wavelength phonon spectrum of the liquid, yielding a characteristic rate of temperature rise.

The interesting thing is that people saw masses of vortex lines in liquid helium for years and wanted to get rid of them," says Zurek.
In this case, the defects materialize as vortex lines -- tiny, invisible whirlpools of fluid that penetrate the liquid helium.
The trouble [with helium] is that you have to work at low temperatures, and you have a fairly hard time finding these vortex lines because you can't see them directly" says Zurek.
