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 in inviscid classical fluids. In quantum flows, circulation is quantized, taking discrete values that are directly related to the number and the orientation of thin vortex filaments enclosed by the path. By varying the size of such closed loop, the circulation provides a measure of the dependence of the flow…

Multifractality breaking from bounded random measures.

It turns out that the linearization effect can be accounted for by Liouville-like random measures defined in terms of upper-bounded scalar fields, and the coarse-grained statistical properties of Gaussian multiplicative chaos are found to be preserved in the linear regime of the scaling exponents.

Velocity circulation intermittency in finite-temperature turbulent superfluid helium

We study intermittency of circulation moments in turbulent superfluid helium by using experimental grid turbulence and numerical simulations of the Hall-Vinen-Bekarevich-Khalatnikov model. More

A statistical formalism for turbulence which has circulation as its main dynamical variable is developed, and one of the most promising attempts to model quark confinement stands on the existence of center vortices.

Vortex clustering, polarisation and circulation intermittency in classical and quantum turbulence

This work links the spatial distribution of vortices in quantum turbulence to the coarse-grained energy dissipation in classical turbulence, enabling the application of existent models of classical turbulence intermittency to the quantum case.

The area rule for circulation in three-dimensional turbulence

It is shown that the hitherto unknown connection between minimal surfaces and turbulence is highlighted, and it is found that circulation statistics match in the two cases only when normalized by an internal variable such as the SD.

Decaying Kolmogorov turbulence in a model of superflow

Superfluid turbulence is studied using numerical simulations of the nonlinear Schrodinger equation (NLSE), which is the correct equation of motion for superflows at low temperatures. This equation

It is shown that singularities of sufficient strength, which are observed to exist in turbulent flow, can lead to nonvanishing dissipation of circulation for an arbitrarily small coarse-graining length in the effective equations, an analog for circulation of Onsager's theorem on energy dissipation for singular Euler solutions.

Circulation in High Reynolds Number Isotropic Turbulence is a Bifractal

The turbulence problem at the level of scaling exponents is hard in part because of the multifractal scaling of small scales, which demands that each moment order be treated and understood

Dual cascade and dissipation mechanisms in helical quantum turbulence

While in classical turbulence helicity depletes nonlinearity and can alter the evolution of turbulent flows, in quantum turbulence its role is not fully understood. We present numerical simulations

We present direct multipoint velocity measurements of the two-dimensional velocity field in the central region of turbulent Rayleigh–Bénard convection. The local homogeneity and isotropy of the

Vortex gas modeling of turbulent circulation statistics.

The model introduced here borrows ideas from the structural approach to turbulence, whereby turbulent flows are depicted as dilute vortex gases, combined with the standard Obukhov-Kolmogorov phenomenological framework of small-scale intermittency, and is able to reproduce key statistical features of circulation, in close agreement with empirical observations compiled from direct numerical simulations.
