The pseudospectral method, in conjunction with a technique for obtaining scaling exponents ζ_{n} from the structure functions S_{n}(r), is presented as an alternative to the extended self-similarity (ESS) method and the use of generalized structure functions. We propose plotting the ratio |S_{n}(r)/S_{3}(r)| against the separation r in accordance with a standard technique for analyzing experimental data. This method differs from the ESS technique, which plots S_{n}(r) against S_{3}(r), with the… 

Scaling exponents saturate in three-dimensional isotropic turbulence

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 moments of velocity

Energy transfer and dissipation in forced isotropic turbulence.

This theoretical work was supplemented by direct numerical simulations of forced isotropic turbulence for integral scale Reynolds numbers up to R(L)=5875 (R(λ)=435), which were used to establish that the decay of dimensionless dissipation with increasing Reynolds number took the form of a power law R( L)(n) with exponent value n=-1.000±0.009.

A formal derivation of the local energy transfer (LET) theory of homogeneous turbulence

A statistical closure of the Navier–Stokes hierarchy which leads to equations for the two-point, two-time covariance of the velocity field for stationary, homogeneous isotropic turbulence is

Assessment of large-scale forcing in isotropic turbulence using a closed Kármán–Howarth equation

We attempt to model the effects of large-scale forcing on the statistical behavior of small scales in isotropic turbulence. More specifically, the effect of large-scale forcing on the second-order

Abstract 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).

Onset criteria for freely decaying isotropic turbulence

From DNS of turbulence decaying from specified initial conditions for the range of initial Taylor-Reynolds numbers 2.58 < R{\lambda}(0) < 358.6, it was found that the shape of the iconic curve of

The effect of Kolmogorov (1962) scaling on the universality of turbulence energy spectra

It has long been established that turbulence energy spectra scale on the Kolmogorov (1941) variables over a wide range of Reynolds numbers and in vastly different physical systems, depending only on

Does intermittency affect the inertial transfer rate in stationary isotropic turbulence?

Direct numerical simulations of the forced Navier-Stokes equations were performed, in which each shell-averaged quantity evolved from a value appropriate to an initial Gaussian state, to fluctuate

Nonuniversality and Finite Dissipation in Decaying Magnetohydrodynamic Turbulence.

The model suggests that the magnitude of cosmological-scale magnetic fields is controlled by the values of the vector field correlations, and can be used to derive similar model equations for other turbulent systems.



Spectral approach to finite Reynolds number effects on Kolmogorov’s 4/5 law in isotropic turbulence

The Kolmogorov’s 4/5 law is often considered as the sole exact relationship of inertial range statistics. Its asymptotic character, however, has been evidenced, investigating the finite Reynolds

Application of extended self-similarity in turbulence

From Navier-Stokes turbulence numerical simulations we show that for the extended self-similarity (ESS) method it is essential to take the third order structure function taken with the modulus and

Reynolds Number Dependence of Energy Spectra in the Overlap Region of Isotropic Turbulence

A Near-Asymptotics analysis of the turbulence energy spectrum is presented that accounts for the effects of finite Reynolds number recently reported by Mydlarski and Warhaft [21]. From dimensional

A parallel pseudospectral code for the direct numerical simulation (DNS) of isotropic turbulence has been developed. The code has been extensively benchmarked using established results from

We performed high-resolution direct numerical simulations (DNS) of incompressible turbulence in a periodic box by using a Fourier spectral method with the number of grid points up to 40963. The

Scaling functions and scaling exponents in turbulence.

This work extends the recent work of Sirovich, Smith, and Yakhot and gets an expression that is uniformly valid for the dissipation as well as the inertial range of scales and enables a more definitive determination of the scaling exponents and intermittency corrections.

Scalar dissipation rate and dissipative anomaly in isotropic turbulence

We examine available data from experiment and recent numerical simulations to explore the supposition that the scalar dissipation rate in turbulence becomes independent of the fluid viscosity when

The third-order structure function is used to study the finite Reynolds number (FRN) effect of turbulence, and it is found that the FRN effect decreases as CR(-mu)(lambda), when R(lambda) is high, and mu < or = 6/5.

This work uses the scaling law of T(p) to study the high-order universal constants of inertial-range scaling, and finds that the available data on scaling exponents favor Kolmogorov's 1941 theory rather than his 1962 theory.
