Coherence, space non-locality and lacunarity in a cascade model of turbulence
Piero Olla, Paolo Paradisi
We use multiscale-multispace correlations and Fourier transform techniques, to study some intermittent random field properties, which escape analysis by structure function scaling.…

Intermittency, synthetic turbulence and wavelet structure functions
Piero Olla, Paolo Paradisi
Some techniques for the study of intermittency by means of wavelet transforms, are presented on an example of synthetic turbulent signal. Several features of the turbulent field, t…
