A Gibbs-like measure for single-time, multi-scale energy transfer in stochastic signals and Shell Model of turbulence
Roberto Benzi, Luca Biferale, Mauro Sbragaglia
A Gibbs-like approach for simultaneous multi-scale correlation functions in random, time-dependent, multiplicative processes for the turbulent energy cascade is investigated. We st…
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…
A simple model for drag reduction
Roberto Benzi, Itamar Procaccia
Direct Numerical Simulations established that the FENE-P model of viscoelastic flows exhibits the phenomenon of turbulent drag reduction which is caused in experiments by dilute po…
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…
Scale by scale budget and similarity laws for shear turbulence
C. M. Casciola, P. Gualtieri, R. Benzi +1
Turbulent shear flows, such as those occurring in the wall region of turbulent boundary layers, manifest a substantial increase of intermittency with respect to isotropic condition…
