Stochastic Shell Model: a model of anomalous scaling and non-Gaussian distribution in turbulence
Hideki Takayasu, Y-h. Taguchi, Tomoo Katsuyama
Abstract
We propose a simple stochastic model of cascading transport in wave number space to clarify the origin of intermittent behavior of fully-developed fluid turbulence. In spite of lack of nonlinearity and viscosity the model gives non-Gaussian fluctuations and multifractal scalings consistent with experimental data.
