Abstract

We study a discrete dissipative dynamical system which presents a transition to turbulence via intermittency. At the instability threshold, this model displays a self-similar structure analogous to that of Mandelbrot's noise models. The 1/f type of spectrum obtained suggests that such spectra can originate from dynamics deterministic in the short term though unpredictable in the long term, which is at the centre of the present understanding of the transition to turbulence.
