The dynamical role of vortices in the two-dimensional inverse cascade of turbulence
V. J. Valadão, R. M. Pereira, L. Moriconi +1
We study the inverse energy cascade of two-dimensional turbulence by means of high-resolution numerical simulations forced at intermediate wavenumbers. To clarify the role of vorti…
Superstatistical Approach to Turbulent Circulation Fluctuations
Henrique S. Lima, Rodrigo M. Pereira, Luca Moriconi +2
Recent investigations of turbulent circulation fluctuations have uncovered substantial insights into the statistical organization of flow structures and revealed unexpected geometr…
Renormalization-group perspective on spontaneous stochasticity
Alexei A. Mailybaev, Luca Moriconi
We present a renormalization-group perspective on spontaneous stochasticity in hydrodynamic turbulence, viewed through the lens of multiscale dynamical systems. Building on previou…
Optimal Surfaces for Turbulent Circulation Statistics
L. Moriconi
We put forward a novel formulation of the vortex gas model of turbulent circulation statistics to address the challenging case of nonplanar circulation contours. Relying upon a fie…
Circulation Fluctuations of Elementary Turbulent Vortices
L. Moriconi, R. M. Pereira
Thin vortex tubes, with core sizes within the dissipation range, profuse in a homogeneous and isotropic turbulent flow. Their intersections with an arbitrary plane define, as a mat…
Vortex polarization and circulation statistics in isotropic turbulence
L. Moriconi, R. M. Pereira, V. J. Valadão
We carry out an in-depth analysis of a recently introduced vortex gas model of homogeneous and isotropic turbulence. Direct numerical simulations are used to provide a concrete phy…
