Large-scale superfluid vortex rings at nonzero temperatures
Daniel H. Wacks, Andrew W. Baggaley, Carlo F. Barenghi
We numerically model experiments in which large-scale vortex rings - bundles of quantized vortex loops - are created in superfluid helium by a piston-cylinder arrangement. We show…
Reconnection dynamics and mutual friction in quantum turbulence
Jason Laurie, Andrew W. Baggaley
We investigate the behaviour of the mutual friction force in finite temperature quantum turbulence in He, paying particular attention to the role of quantized vortex reconnecti…
A note on the propagation of quantized vortex rings through a quantum turbulence tangle: Energy transport or energy dissipation?
Jason Laurie, Andrew W. Baggaley
We investigate quantum vortex ring dynamics at scales smaller than the inter-vortex spacing in quantum turbulence. Through geometrical arguments and high resolution numerical simul…
Local and nonlocal dynamics in superfluid turbulence
L. K. Sherwin-Robson, C. F. Barenghi, A. W. Baggaley
Turbulence in superfluid helium~II is a tangle of quantized vortex lines which interact via the classical Biot-Savart law. We show that vortex tangles with the same vortex line den…
Helicity transfer during quantised vortex reconnection
Andrew W. Baggaley
We consider the reconnection of two untwisted, linked quantised vortex rings in a Bose-Einstein condensate. We show that the reconnection is capable of transferring helicity, from…
Acceleration statistics in thermally driven superfluid turbulence
Andrew W. Baggaley, Carlo F. Barenghi
New methods of flow visualization near absolute zero have opened the way to directly compare quantum turbulence (in superfluid helium) to classical turbulence (in ordinary fluids s…
