Developing homogeneous isotropic turbulence [PDF]
Physica D: Nonlinear Phenomena, 2012 We investigate the self-similar evolution of the transient energy spectrum which precedes the establishment of the Kolmogorov spectrum in homogeneous isotropic turbulence in three dimensions using the EDQNM closure model. The transient evolution exhibits self-similarity of the second kind and has a non-trivial dynamical scaling exponent which results ...

Floc Size Distributions of Cohesive Sediment in Homogeneous Isotropic Turbulence
Frontiers in Earth Science, 2022 Floc size distribution is one of the key parameters to characterize flocculating cohesive sediment. An Eulerian–Lagrangian framework has been implemented to study the flocculation dynamics of cohesive sediments in homogeneous isotropic turbulent flows ...

Clustering of vertically constrained passive particles in homogeneous, isotropic turbulence [PDF]
, 2014 We analyze the dynamics of small particles vertically confined, by means of a linear restoring force, to move within a horizontal fluid slab in a three-dimensional (3D) homogeneous isotropic turbulent velocity field. The model that we introduce and study

Information production in homogeneous isotropic turbulence [PDF]
Physical Review E, 2019 We study the Reynolds number scaling of the Kolmogorov-Sinai entropy and attractor dimension for three dimensional homogeneous isotropic turbulence through the use of direct numerical simulation. To do so, we obtain Lyapunov spectra for a range of different Reynolds numbers by following the divergence of a large number of orthogonal fluid trajectories.

Energy transfer and vortex structures: visualizing the incompressible turbulent energy cascade
New Journal of Physics, 2023 The transfer of kinetic energy from large to small scales is a hallmark of turbulent flows. Yet, a precise mechanistic description of this transfer, which is expected to occur via an energy cascade, is still missing.

Cloud droplet diffusional growth in homogeneous isotropic turbulence: bin microphysics versus Lagrangian super-droplet simulations [PDF]
Atmospheric Chemistry and Physics, 2021 The increase in the spectral width of an initially monodisperse population of cloud droplets in homogeneous isotropic turbulence is investigated by applying a finite-difference fluid flow model combined with either Eulerian bin microphysics or a ...

Probability Density Functions in Homogeneous and Isotropic Magneto-Hydrodynamic Turbulence
Atmosphere, 2020 We derive a hierarchy of evolution equations for multi-point probability density functions in magneto-hydrodynamic (MHD) turbulence. We discuss the relation to the moment hierarchy in MHD turbulence formulated by Chandrasekhar (S. Chandrasekhar, Proc. R.

On the thixotropic effect of turbulence
Theoretical and Applied Mechanics Letters, 2019 As a follow-up research of the work on the natural viscosity of turbulence of Huang et al. [Journal of Turbulence (2003)], here we investigate the thixotropic effect of a turbulent Newtonian fluid on the basis of the ensemble-averaged Navier–Stokes ...
