Scale invariance of intermittency in LES turbulence
B. Magacho, S. Thalabard, M. Buzzicotti +3
Turbulent flows exhibit large intermittent fluctuations from inertial to dissipative scales, characterized by multifractal statistics and breaking the statistical self-similarity.…

Coherent Structures and Lattice-Boltzmann Hydrodynamics in Turbulent Pipe Flows
B. Magacho
Coherent structures (CS) are known to be part of the foundations of turbulent flow dynamics. For a long time, their appearance was believed to be chaotic and unorganized. However,…

Persistence of large scale coherent structures in a turbulent pipe flow through an improved lattice Boltzmann approach
B. Magacho, L. Moriconi, J. B. R. Loureiro
We simulated a turbulent pipe flow within the Lattice Boltzmann Method using a multiple-relaxation-time collision operator with Maxwell-Boltzmann equilibrium distribution expanded,…
