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.

Inertial spheroids in homogeneous, isotropic turbulence. [PDF]
Physical Review E, 2018 We study the rotational dynamics of inertial disks and rods in three-dimensional, homogeneous, isotropic turbulence. In particular, we show how the alignment and the decorrelation timescales of such spheroids depend, critically, on both the level of ...

Spinodal Decomposition in Homogeneous and Isotropic Turbulence [PDF]
Physical Review Letters, 2013 We study the competition between domain coarsening in a symmetric binary mixture below critical temperature and turbulent fluctuations. We find that the coarsening process is arrested in the presence of turbulence.

Lagrangian Cascade in Three-Dimensional Homogeneous and Isotropic Turbulence [PDF]
Journal of Fluid Mechanics, 2014 In this work, the scaling statistics of the dissipation along Lagrangian trajectories are investigated by using fluid tracer particles obtained from a high resolution direct numerical simulation with $Re_{\lambda}=400$. Both the energy dissipation rate $\

Scaling of Lyapunov exponents in homogeneous isotropic turbulence [PDF]
Physical Review Fluids, 2015 Lyapunov exponents measure the average exponential growth rate of typical linear perturbations in a chaotic system, and the inverse of the largest exponent is a measure of the time horizon over which the evolution of the system can be predicted.

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 ...

Clustering of vector nulls in homogeneous isotropic turbulence [PDF]
Physical Review Fluids, 2020 We analyze the vector nulls of velocity, Lagrangian acceleration, and vorticity, coming from direct numerical simulations of forced homogeneous isotropic turbulence at $Re_\lambda \in [40-610]$.

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 ...
