Lattice Boltzmann method at finite-Knudsen numbers
Federico Toschi, Sauro Succi
A modified lattice Boltzmann model with a stochastic relaxation mechanism mimicking "virtual'' collisions between free-streaming particles and solid walls is introduced. This modif…
Rayleigh and Prandtl number scaling in the bulk of Rayleigh-Benard turbulence
Enrico Calzavarini, Detlef Lohse, Federico Toschi +1
The Rayleigh (Ra) and Prandtl (Pr) number scaling of the Nusselt number Nu, the Reynolds number Re, the temperature fluctuations, and the kinetic and thermal dissipation rates is s…
A lattice Boltzmann study of non-hydrodynamic effects in shell models of turbulence
R. Benzi, L. Biferale, M. Sbragaglia +2
A lattice Boltzmann scheme simulating the dynamics of shell models of turbulence is developed. The influence of high order kinetic modes (ghosts) on the dissipative properties of t…
Multifractal statistics of Lagrangian velocity and acceleration in turbulence
L. Biferale, G. Boffetta, A. Celani +3
The statistical properties of velocity and acceleration fields along the trajectories of fluid particles transported by a fully developed turbulent flow are investigated by means o…
Lagrangian statistics in fully developed turbulence
L. Biferale, G. Boffetta, A. Celani +2
The statistical properties of fluid particles transported by a fully developed turbulent flow are investigated by means of high resolution direct numerical simulations. Single traj…
Effects of forcing in three dimensional turbulent flows
Luca Biferale, Alessandra Lanotte, Federico Toschi
We present the results of a numerical investigation of three-dimensional homogeneous and isotropic turbulence, stirred by a random forcing with a power law spectrum, $E_f(k)\sim k^…
