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…

Kolmogorov and Kelvin wave cascades in a generalized model for quantum turbulence
Nicolás Pablo Müller, Giorgio Krstulovic
We performed numerical simulations of decaying quantum turbulence by using a generalized Gross-Pitaevskii equation, that includes a beyond mean field correction and a nonlocal inte…
