Velocity circulation intermittency in finite-temperature turbulent superfluid helium
Nicolás P. Müller, Yuan Tang, Wei Guo +1
We study intermittency of circulation moments in turbulent superfluid helium by using experimental grid turbulence and numerical simulations of the Hall-Vinen-Bekarevich-Khalatniko…
Intermittency of velocity circulation in quantum turbulence
Nicolás P. Müller, Juan Ignacio Polanco, Giorgio Krstulovic
The velocity circulation, a measure of the rotation of a fluid within a closed path, is a fundamental observable in classical and quantum flows. It is indeed a Lagrangian invariant…
Quantum vortex reconnections mediated by trapped particles
Umberto Giuriato, Giorgio Krstulovic
Reconnections between quantum vortex filaments in presence of trapped particles are investigated using numerical simulations of the Gross--Pitaevskii equation. Particles are descri…
Counterflow-Induced Inverse Energy Cascade in Three-Dimensional Superfluid Turbulence
Juan Ignacio Polanco, Giorgio Krstulovic
Finite-temperature quantum turbulence is often described in terms of two immiscible fluids that can flow with a non-zero mean relative velocity. Such out-of-equilibrium state is kn…
A matching theory to characterize sound emission during vortex reconnection in quantum fluids
Davide Proment, Giorgio Krstulovic
In a concurrent work, Villois et al. 2020 reported the evidence that vortex reconnections in quantum fluids follow an irreversible dynamics, namely vortices separate faster than th…
Active and finite-size particles in decaying quantum turbulence at low temperature
Umberto Giuriato, Giorgio Krstulovic
The evolution of a turbulent tangle of quantum vortices in presence of finite-size active particles is studied by means of numerical simulations of the Gross-Pitaevskii equation. P…
