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…
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…
Coherent Organizational States in Turbulent Pipe Flow at moderate Reynolds numbers
R. Jäckel, B. Magacho, B. E. Owolabi +3
Turbulent pipe flow is still an essentially open area of research, boosted in the last two decades by considerable progress achieved both on the experimental and numerical frontier…
