Stochastic selfsimilar branching and turbulence

A new stochastic multifractal cascade model for inertial-subrange turbulence is introduced which can be fitted to a recent experimental determination of the spectrum of generalized dimensions. The local scaling behaviour (set of scale-invariant multiplier distributions) is close to the observed one. The model also produces realistic energy-dissipation-rate signals and displays the correct square-root exponentional tails in the energy-flux probability densities.
