A thermodynamical approach to dissipation range turbulence
Jacopo Bellazzini
A model to explain the statistics of the velocity gradients in the dissipation range of a turbulent flow is presented. The experimentally observed non-gaussian statistics is theore…
Aging Induced Multifractality
P. Allegrini, J. Bellazzini, G. Bramanti +3
We show that the dynamic approach to Lévy statistics is characterized by aging and multifractality, induced by an ultra-slow transition to anomalous scaling. We argue that these as…
Holder regularity and chaotic attractors
Jacopo Bellazzini
We demonstrate how the Holder regularity of a given signal is a lower bound for the Grassberger-Procaccia correlation dimension of strange attractors.
Wavelet Cross-Correlation Analysis of Turbulent Mixing from Large-Eddy-Simulations
Stefano Sello, Jacopo Bellazzini
The complex interactions existing between turbulence and mixing in a bluff-body stabilised flame configuration is investigated by means of a wavelet cross-correlation analysis on L…
