Intermittency in Turbulence: Multiplicative random process in space and time
نویسندگان
چکیده
We present a simple stochastic algorithm for generating multiplicative processes with multiscaling both in space and in time. With this algorithm we are able to reproduce a synthetic signal with the same space and time correlation as the one coming from shell models for turbulence and the one coming from a turbulent velocity field in a quasi-Lagrangian reference frame.

On Estimation Theory for Multiplicative Cascades
The notion of multiplicative cascade was introduced into the statistical theory of turbulence by A.N. Kolmogorov as a phenomenological framework intended to accommodate the intermittency and large fluctuations observed in turbulent fluid flows. The basic idea is that energy is redistributed from larger to smaller scales via a splitting mechanism involving random multiplicative factors known as ...
متن کاملA Mthod for Generating the Turbulent Intermittency Function
A detection method based on sensitization of a squared double differentiated signal is developed which discriminates the turbulent zones from laminar zones quite accurately. The procedure adopts a variable threshold and a variable hold time of the order of the Kolmogorov time scale. The output file so generated, includes all the information for further analysis of the turbulent signal.
متن کاملAmplitude-phase Synchronization in Intermittent Turbulence and Spatiotemporal Chaos
The solar-terrestrial environment provides a natural laboratory for observing intermittent turbulence [1]. The degree of non-Gaussianity (intermittency) in a turbulence can be quantified by calculating the normalized fourth-order structure function, also known as kurtosis. Recently, a phase coherence surrogate technique for characterizing phase synchronization was developed for space plasmas [2...
متن کاملUncovering latent singularities from multifractal scaling laws in mixed asymptotic regime. Application to turbulence
In this paper we revisit an idea originally proposed by Mandelbrot about the possibility to observe “negative dimensions” in random multifractals. For that purpose, we define a new way to study scaling where the observation scale l and the total sample length L are respectively going to zero and to infinity. This “mixed” asymptotic regime is parametrized by an exponent χ that corresponds to Man...
متن کاملMultifractal Fluctuations in Finance
We consider the structure functions S (q) (τ), i.e. the moments of order q of the increments X(t + τ) − X(t) of the Foreign Exchange rate X(t) which give clear evidence of scaling (S (q) (τ) ∝ τ ζ(q)). We demonstrate that the nonlinearity of the observed scaling exponent ζ(q) is incompatible with monofractal additive stochastic models usually introduced in finance: Brownian motion, Levy process...
