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…
Intermittency in Turbulence: computing the scaling exponents in shell models
Roberto Benzi, Luca Biferale, Mauro Sbragaglia +1
We discuss a stochastic closure for the equation of motion satisfied by multi-scale correlation functions in the framework of shell models of turbulence. We give a systematic proce…
Intermittency in Turbulence: Multiplicative random process in space and time
Roberto Benzi, Luca Biferale, Federico Toschi
We present a simple stochastic algorithm for generating multiplicative processes with multiscaling both in space and in time. With this algorithm we are able to reproduce a synthet…
Homogeneous isotropic turbulence in dilute polymers: scale by scale budget
E. De Angelis, C. M. Casciola, R. Benzi +1
The turbulent energy cascade in dilute polymers solution is addressed here by considering a direct numerical simulation of homogeneous isotropic turbulence of a FENE-P fluid in a t…
Scaling laws and intermittency in homogeneous shear flow
P. Gualtieri, C. M Casciola, R. Benzi +2
In this paper we discuss the dynamical features of intermittent fluctuations in homogeneous shear flow turbulence. In this flow the energy cascade is strongly modified by the produ…
