Double Multiple-Relaxation-Time model of Lattice-Boltzmann Magnetohydrodynamics at Low Magnetic Reynolds Numbers
Bruno Magacho, Hugo Saraiva Tavares, Luca Moriconi +1
We develop an improved lattice-Boltzmann numerical scheme to solve magnetohydrodynamic (MHD) equations in the regime of low magnetic Reynolds numbers, grounded on a manifestly Gali…
A simplified lattice Boltzmann implementation of the quasi-static approximation in pipe flows under the presence of non-uniform magnetic fields
Hugo S. Tavares, Bruno Magacho, Luca Moriconi +1
We propose a single-step simplified lattice Boltzmann algorithm capable of performing magnetohydrodynamic (MHD) flow simulations in pipes for very small values of magnetic Reynolds…
Eddy-Viscous Modeling and the Topology of Extreme Circulation Events in Three-Dimensional Turbulence
G. B. Apolinário, L. Moriconi, R. M. Pereira +1
We discuss the role of particular velocity field configurations -- instantons, for short -- which are supposed to dominate the flow during the occurrence of extreme turbulent circu…
Circulation Statistics and the Mutually Excluding Behavior of Turbulent Vortex Structures
Luca Moriconi, Rodrigo M. Pereira, Victor J. Valadão
The small-scale statistical properties of velocity circulation in classical homogeneous and isotropic turbulent flows are assessed through a modeling framework that brings together…
Statistics of Extreme Turbulent Circulation Events from Multifractality Breaking
L. Moriconi, R. M. Pereira
Recent numerical explorations of extremely intense circulation fluctuations at high Reynolds number flows have brought to light novel aspects of turbulent intermittency. Vortex gas…
