Whither the Zeroth Law of Turbulence?
Kartik P. Iyer, Theodore D. Drivas, Gregory L. Eyink +1
Experimental and numerical studies of incompressible turbulence suggest that the mean dissipation rate of kinetic energy remains constant as the Reynolds number tends to infinity (…
Scaling exponents saturate in three-dimensional isotropic turbulence
Kartik P. Iyer, Katepalli R. Sreenivasan, P. K. Yeung
From a database of direct numerical simulations of homogeneous and isotropic turbulence, generated in periodic boxes of various sizes, we extract the spherically symmetric part of…
Fractal iso-level sets in high-Reynolds-number scalar turbulence
Kartik P. Iyer, Jörg Schumacher, Katepalli R. Sreenivasan +1
We study the fractal scaling of iso-levels sets of a passive scalar mixed by three-dimensional homogeneous and isotropic turbulence at high Reynolds numbers. The Schmidt number is…
Circulation in high Reynolds number isotropic turbulence is a bifractal
Kartik P. Iyer, Katepalli R. Sreenivasan, P. K. Yeung
The turbulence problem at the level of scaling exponents is hard in part because of the multifractal scaling of small scales, which demands that each moment order be treated and un…
Self-similar Subgrid-scale Models for Inertial Range Turbulence and Accurate Measurements of Intermittency
Luca Biferale, Fabio Bonaccorso, Michele Buzzicotti +1
A class of spectral subgrid models based on a self-similar and reversible closure is studied with the aim to minimize the impact of subgrid scales on the inertial range of fully de…
Scaling of locally averaged energy dissipation and enstrophy density in isotropic turbulence
Kartik P Iyer, Jörg Schumacher, Katepalli R Sreenivasan +1
Using direct numerical simulations of isotropic turbulence in periodic cubes of several sizes, the largest being yielding a microscale Reynolds number of , we study…
