Journal ArticleDOI
On the multifractal nature of fully developed turbulence and chaotic systems
TL;DR: In this paper, the authors review the concept of multifractal sets in both turbulent flows and dynamical systems using a generalisation of the beta-model and propose that the energy dissipation of three-dimensional turbulent flow is concentrated on a set with non-integer Hausdorff dimension.
Journal ArticleDOI
Predictability in the large: an extension of the concept of Lyapunov exponent
TL;DR: In this article, a finite-size Lyapunov exponent was introduced to measure the growth rate of finite size perturbations, which coincides with the size of the perturbation.
Journal ArticleDOI
Growth of Noninfinitesimal Perturbations in Turbulence.
TL;DR: A measure of the chaoticity degree associated to a given scale of the velocity field is introduced, generalizing the usual concept of maximum Lyapunov exponent, and it is found that the scaling exponent is not sensitive to intermittency corrections, but is an invariant of the multifractal models.
Journal ArticleDOI
Stochastic resonance in deterministic chaotic systems
TL;DR: In this paper, the authors proposed a mechanism which produces periodic variations of the degree of predictability in dynamical systems, and showed that even in the absence of noise when the control parameter changes periodically in time, below and above the threshold for the onset of chaos, stochastic resonance effects appear.
Journal ArticleDOI
Transition to chaos in a shell model of turbulence
TL;DR: In this paper, a modified shell model for the energy cascade in three-dimensional turbulence was proposed by varying the coefficients of the non-linear terms in such a way that the fundamental symmetries of Navier-Stokes are conserved.
