In this paper, an experimental velocity database of a bacterial collective motion, e.g., Bacillus subtilis, in turbulent phase with volume filling fraction 84% provided by Professor Goldstein at Cambridge University (UK), was analyzed to emphasize the scaling behavior of this active turbulence system. This was accomplished by performing a Hilbert-based methodology analysis to retrieve the scaling property without the β-limitation. A dual-power-law behavior separated by the viscosity scale ℓ_…

Intrinsic flow structure and multifractality in two-dimensional bacterial turbulence.

Surprisingly the scaling extracted from the streamline segment indicates the existence of scale similarity even at the zero Reynolds number limit, and the lognormal statistics is verified for the coarse-grained energy dissipation and enstrophy, which supports thelognormal formula to fit the measured scaling exponent.

Turbulent lithosphere deformation in the Tibetan Plateau.

It is shown that the Tibetan Plateau deformation demonstrates turbulence-like statistics, e.g., spatial invariance across continuous scales, and a dual-power-law behavior is evident to show the existence of two possible conservation laws for the enstrophy- like cascade and kinetic-energy-like cascade in the range 50≲r≲500km.

Kolmogorovian Active Turbulence of a Sparse Assembly of Interacting Marangoni Surfers

Active matter, composed of self-propelled entities, forms a wide class of out-of-equilibrium systems that display striking collective behaviors, among which, the so-called active turbulence where

Stratified Kelvin–Helmholtz turbulence of compressible shear flows

Abstract. We study scaling laws of stratified shear flows by performing high-resolution numerical simulations of inviscid compressible turbulence induced by Kelvin–Helmholtz instability. An implicit



Two-scale correlation and energy cascade in three-dimensional turbulent flows

In this paper, we propose a high-order harmonic-free methodology, namely arbitrary-order Hilbert spectral analysis, to estimate the two-scale correlation (TSC). When applied to fully developed

Investigation of the self-propelled two-dimensional turbulent flows of Escherichia coli suspensions in thin liquid films finds that the flow has fluctuating vortices with a broad range of scales and intensities through the nonlinear interaction of the swimming bacteria.

Hilbert statistics of vorticity scaling in two-dimensional turbulence

In this paper, the scaling property of the inverse energy cascade and forward enstrophy cascade of the vorticity filed ω(x, y) in two-dimensional (2D) turbulence is analyzed. This is accomplished by

Meso-scale turbulence in living fluids

The authors' experimental results for the bacterial flow statistics agree well with predictions from a minimal model for self-propelled rods, suggesting that at high concentrations the collective motion of the bacteria is dominated by short-range interactions.

The multifractal nature of turbulent energy dissipation

The intermittency of the rate of turbulent energy dissipation ε is investigated experimentally, with special emphasis on its scale-similar facets. This is done using a general formulation in terms of

Small-Scale Properties of Turbulent Rayleigh-Bénard Convection

The properties of the structure functions and other small-scale quantities in turbulent Rayleigh-Benard convection are reviewed, from an experimental, theoretical, and numerical point of view. In

Second-order structure function in fully developed turbulence.

An analysis of passive scalar (temperature) turbulence time series is presented to show the influence of large-scale structures in real turbulence and the efficiency of the Hilbert-based methodology, and corresponding scaling exponents ζ(θ)(q) provided by the Hilbert -based approach indicate that the Passive scalar turbulence field may be less intermittent than what was previously believed.

Fluid dynamics of bacterial turbulence.

Velocimetry of bacteria and surrounding fluid, determined by imaging cells and tracking colloidal tracers, yields consistent results for velocity statistics and correlations over 2 orders of magnitude in kinetic energy, revealing a decrease of fluid memory with increasing swimming activity and linear scaling between kinetic energy and enstrophy.

An amplitude-frequency study of turbulent scaling intermittency using Empirical Mode Decomposition and Hilbert Spectral Analysis

Hilbert-Huang transform is a method that has been introduced recently to decompose nonlinear, nonstationary time series into a sum of different modes, each one having a characteristic frequency. Here


Small-scale turbulence has been an area of especially active research in the recent past, and several useful research directions have been pursued. Here, we selectively review this work. The emphasis
