Inverse energy transfer in three-dimensional quantum vortex flows
Piotr Z. Stasiak, Andrew Baggaley, Carlo. F. Barenghi +2
Vortex reconnections play a fundamental role in fluids.They increase the complexity of flow and develop small-scale motions.In this work, we report that in superfluids, they can al…
Cross-Component Energy Transfer in Superfluid Helium-4
Piotr Z. Stasiak, Andrew W. Baggaley, Giorgio Krstulovic +2
The reciprocal energy and enstrophy transfers between normal fluid and superfluid components dictate the overall dynamics of superfluid He including the generation, evolution a…
Vorticity Locking and Pressure Dynamics in Finite-Temperature Superfluid Turbulence
Jason Laurie, Andrew W. Baggaley
We present a numerical study of finite-temperature superfluid turbulence using the vortex filament model for superfluid helium. We examine the phenomenon of vorticity locking betwe…
Dissipation anomaly in a turbulent quantum fluid
Luca Galantucci, Em Rickinson, Andrew W. Baggaley +2
When the intensity of turbulence is increased (by increasing the Reynolds number, e.g. by reducing the viscosity of the fluid), the rate of the dissipation of kinetic energy decrea…
Superfluid turbulence driven by cylindrically symmetric thermal counterflow
E. Rickinson, C. F. Barenghi, Y. A. Sergeev +1
We show by direct numerical simulations that the turbulence generated by steadily heating a long cylinder immersed in helium~II is strongly inhomogeneous and consists of a dense tu…
A new self-consistent approach of quantum turbulence in superfluid helium
Luca Galantucci, Andrew W. Baggaley, Carlo F. Barenghi +1
We present the Fully cOUpled loCAl model of sUperfLuid Turbulence (FOUCAULT) that describes the dynamics of finite temperature superfluids. The superfluid component is described by…
