Eddy diffusivity operator in homogeneous isotropic turbulence

Physical Review Fluids, 2019
We use the recently developed Macroscopic Forcing Method [Mani and Park, Physical Review Fluids, 6:054607, 2021] to compute the scale-dependent eddy diffusivity characterizing ensemble-averaged scalar and momentum transport in incompressible homogeneous ...

Evolution of the velocity gradient invariants in homogeneous isotropic turbulence with an inverse energy cascade

The Physics of Fluids, 2023
An investigation of topological features of homogeneous isotropic turbulence with an inverse energy cascade is performed by using a direct numerical simulation (DNS).

Effect of long-range Coulomb repulsion on adhesive particle agglomeration in homogeneous isotropic turbulence

Journal of Fluid Mechanics, 2021
We conduct numerical investigations on the early-stage agglomeration of identically charged microparticles in homogeneous isotropic turbulence. The turbulent flow field is evolved by direct numerical simulation, and the adhesive discrete element method ...

Kármán–Howarth solutions of homogeneous isotropic turbulence

Journal of Fluid Mechanics, 2021
The Kármán–Howarth equation (KHEq) is solved using a closure model to obtain solutions of the second-order moment of the velocity increment, $S_2$ , in homogeneous isotropic turbulence (HIT). The results are in good agreement with experimental data for decaying turbulence and are also consistent with calculations based on the
