Density Fluctuations in MHD turbulence : spectra , intermittency and topology
We perform 3D compressible MHD simulations for an extended range of sonic and Alfvén Mach numbers and analyze the statistics of 3D density and 2D column density, which includes probability distribution functions, spectra, skewness, kurtosis, She-Lévêque exponents and genus. In order to establish the relation between the statistics of the observables, i.e. column densities, and the underlying 3D...
متن کامل20 07 Density Fluctuations in MHD turbulence : spectra , intermittency and topology
We perform three-dimensional (3D) compressible MHD simulations over many dynamical times for an extended range of sonic and Alfvén Mach numbers and analyze the statistics of 3D density and 2D column density, which include probability distribution functions, spectra, skewness, kurtosis, She-Lévêque exponents, and genus. In order to establish the relation between the statistics of the ob-servable...
متن کاملAspects of Density Fluctuations in Compressible MHD Turbulence
We study scaling relations of compressible isothermal strongly magnetized turbulence using numerical simulations with resolution 5123. We find a good correspondence of our results with the Fleck (1996) model of compressible hydrodynamic turbulence. In particular, we find that the density-weighted velocity, i.e. u ≡ ρ1/3v, proposed in Kritsuk et al. (2007) obeys the Kolmogorov scaling, i.e. Eu(k...
متن کاملIntermittency in MHD turbulence and coronal nanoflares modelling
High resolution numerical simulations, solar wind data analysis, and measurements at the edges of laboratory plasma devices have allowed for a huge progress in our understanding of MHD turbulence. The high resolution of solar wind measurements has allowed to characterize the intermittency observed at small scales. We are now able to set up a consistent and convincing view of the main properties...
متن کاملVortex-density fluctuations, energy spectra, and vortical regions in superfluid turbulence.
Measurements of the energy spectrum and of the vortex-density fluctuation spectrum in superfluid turbulence seem to contradict each other. Using a numerical model, we show that at each instance of time the total vortex line density can be decomposed into two parts: one formed by metastable bundles of coherent vortices, and one in which the vortices are randomly oriented. We show that the former...
