There is some evidence to suggest that the atmosphere does not always obey Kolmogorov’s 11 3 power law (e.g. [19, 20, 21]). It is sometimes found to be lower than 11 3 but rarely higher. Boreman and Dainty generalised the 3D power spectrum for any power exponent, β. COMPARISON OF SPECTRAL SLOPES OF MAGNETOHYDRODYNAMIC AND ...

Beresnyak, A. Lazarian Dept. of Astronomy, Univ. of Wisconsin, Madison, WI 53706 Draft version July 16, 2009 ABSTRACT We performed a series of high resolution (up to 10243 ) direct ... STATIONARY SPECTRA OF WEAK WAVE TURBULENCE 3 Stationary Spectra of Weak Wave Turbulence This is key chapter of the first volume. Here we deal with stationary dis tributions of weak turbulence. In Sections 3.1–4 we describe the universal Kolmogorov like spectra in the inertial interval. We obtain the Kolmogorov spectra as exact solutions of kinetic equations for scale invariant media, Theories of convection and the spectrum of turbulence in ... Theories of convection and the spectrum of turbulence in the solar photosphere 3 forcing damping term in the Kolmogorov equation. BO59 should hold for r LB, while K41 predictions should be observed for r LB, leading to a priori observable kinks in both velocity and temperature spectra. Chapter 7 Basic Turbulence Department of Astronomy Chapter 7 Basic Turbulence The universe is a highly turbulent place, and we must understand turbulence if we want to understand a lot of what’s going on. Interstellar turbulence causes the “twinkling” of radio sources, just as turbulence in the earth’s atmosphere causes the twinkling of stars. Turbulence in stellar atmospheres [cond mat 0508624] Kolmogorov Spectrum of Quantum Turbulence Second, to obtain steady turbulence through the balance between injection and decay, we add energy injection at large scales. The energy spectrum is quantitatively consistent with the Kolmogorov law in both decaying and steady turbulence. Consequently, this is the first study that confirms the inertial range of quantum turbulence. A non Gaussian phenomenological model for higher order ... An extended Kolmogorov phenomenology for the dimensional analysis of the energy spectrum has been introduced by Kraichnan [Phys. Fluids 8 (1965) 1385]. Kraichnan s ideas are here extended to show how the higher order spectral moments can scale as k − 5 3, for any order and without the assumption of a Gaussian process. Particle acceleration by large scale turbulence Particle acceleration by large scale turbulence 33RD INTERNATIONAL COSMIC RAY CONFERENCE, RIO DE JANEIRO 2013 time and tv is the particle mean free path. The first four terms of Equation (1) are the same as the Parker equation and the fifth term describes the shear acceleration.

Kolmogorov Spectra of Turbulence I | SpringerLink We shall show how the initial cascade hypothesis turns into an elegant theory yielding the Kolmogorov spectra of turbulence as exact solutions. We shall describe the further development of the theory discussing stability prob­ lems and modes of Kolmogorov spectra formation, as well as their matching with sources and sinks.

Kolmogorov Spectra in One Dimensional Weak ... On velocity and reactive scalar spectra in turbulent ... scalar spectra in turbulent premixed flames are the experimental works of Guttenfelder et al. (2003) and Kariuki et al. (2012) who report spectra of hydroxyl radical. Little is known of spectra and co spectra of reacting scalars at realistic levels of heat release in premixed flames, as noted by Dimotakis (2005) and Knaus Pantano (2009 ....

(PDF) Energy Spectra of Developed Turbulence in Helium ... This description is valid for the scales greater that the mean distance ℓ separating the quantised vortices. For example, in 4 He above 1.5 K the normal fluid Kolmogorov scale appears to be of the same order as ℓ and, therefore, in this case our model is not applicable for predicting the superfluid spectrum below the Kolmogorov scale1 . ...
