Anomalous Scaling in a Model of Hydrodynamic Turbulence with a Small Parameter
Daniela Pierotti, Victor S. L'vov, Anna Pomyalov +1
The major difficulty in developing theories for anomalous scaling in hydrodynamic turbulence is the lack of a small parameter. In this Letter we introduce a shell model of turbulen…
Anomalous Scaling from Controlled Closure in a Shell Model of Turbulence
Victor S. L'vov, Daniela Pierotti, Anna Pomyalov +1
We present a model of hydrodynamic turbulence for which the program of computing the scaling exponents from first principles can be developed in a controlled fashion. The model con…
Helicity advection in Turbulent Models
L. Biferale, D. Pierotti, F. Toschi
Helicity transfer in a shell model of turbulence is investigated. In particular, we study the scaling behavior of helicity transfer in a dynamical model of turbulence lacking inver…
Time-reversible Dynamical Systems for Turbulence
L. Biferale, D. Pierotti, A. Vulpiani
Dynamical Ensemble Equivalence between hydrodynamic dissipative equations and suitable time-reversible dynamical systems has been investigated in a class of dynamical systems for t…
Helicity Transfer in Turbulent Models
L. Biferale, D. Pierotti, F. Toschi
Helicity transfer in a shell model of turbulence is investigated. We show that a Reynolds-independent helicity flux is present in the model when the large scale forcing breaks inve…
Intermittency in the large N-limit of a spherical shell model for turbulence
D. Pierotti
A spherical shell model for turbulence, obtained by coupling replicas of the Gledzer, Okhitani and Yamada shell model, is considered. Conservation of energy and of an helicity-…
