Statistics of small scale vortex filaments in turbulence
Luca Biferale, Andrea Scagliarini, Federico Toschi
We study the statistical properties of coherent, small-scales, filamentary-like structures in Turbulence. In order to follow in time such complex spatial structures, we integrate L…
Fully developed turbulence and the multifractal conjecture
R. Benzi, L. Biferale
We review the Parisi-Frisch MultiFractal formalism for Navier--Stokes turbulence with particular emphasis on the issue of statistical fluctuations of the dissipative scale. We do i…
Caustics and Intermittency in Turbulent Suspensions of Heavy Particles
J. Bec, L. Biferale, M. Cencini +2
The statistics of velocity differences between very heavy inertial particles suspended in an incompressible turbulent flow is found to be extremely intermittent. When particles are…
Eulerian and Lagrangian Statistics from high resolution Numerical Simulations of weakly compressible turbulence
R. Benzi, L. Biferale, R. Fisher +2
We report a detailed study of Eulerian and Lagrangian statistics from high resolution Direct Numerical Simulations of isotropic weakly compressible turbulence. Reynolds number at t…
Lattice Boltzmann method with self-consistent thermo-hydrodynamic equilibria
M. Sbragaglia, R. Benzi, L. Biferale +3
Lattice kinetic equations incorporating the effects of external/internal force fields via a shift of the local fields in the local equilibria, are placed within the framework of co…
Hydrokinetic simulations of nanoscopic precursor films in rough channels
S. Chibbaro, L. Biferale, K. Binder +4
We report on simulations of capillary filling of high-wetting fluids in nano-channels with and without obstacles. We use atomistic (molecular dynamics) and hydrokinetic (lattice-Bo…
