Analysis of inertial-range intermittency in forward and inverse cascade regions in isotropic turbulence
H. Yao, M. Schnaubelt, A. Lubonja +10
In order to test the hypothesis that inverse cascade regions in turbulent flows might exhibit more Gaussian noise-like and less intermittent small-scale statistics compared to the…
Oscillations Modulating Power Law Exponents in Isotropic Turbulence: Comparison of Experiments with Simulations
Kartik P. Iyer, Gregory P. Bewley, Luca Biferale +2
Inertial-range features of turbulence are investigated using data from experimental measurements of grid turbulence and direct numerical simulations of isotropic turbulence simulat…
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…
Extreme velocity gradients in turbulent flows
Dhawal Buaria, Alain Pumir, Eberhard Bodenschatz +1
Fully turbulent flows are characterized by intermittent formation of very localized and intense velocity gradients. These gradients can be orders of magnitude larger than their typ…
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…
