Magnetized decaying turbulence in the weakly compressible Taylor-Green vortex

چکیده

Magnetohydrodynamic turbulence affects both terrestrial and astrophysical plasmas. The properties of magnetized must be better understood to more accurately characterize these systems. This work presents ideal MHD simulations the compressible Taylor-Green vortex under a range initial sub-sonic Mach numbers magnetic field strengths. We find that regardless strength, energy becomes dominant over kinetic on all scales after at most several dynamical times. spectral indices spectra become shallower than $k^{-5/3}$ time generally fluctuate. Using shell-to-shell transfer analysis framework, we fields facilitate significant amount flux cascade is suppressed. Moreover, observe nonlocal from large scale intermediate small via tension. conclude even in intermittently or singularly driven weakly systems, effects cannot neglected.

Transport Coefficients in Rotating Weakly Compressible Turbulence

Analytical studies of compressible turbulence have found that compressible velocity fluctuations create both effective fluid transport properties and an effective equation of state. This paper investigates the effects of rotation on compressible turbulence. It is shown that rotation modifies the transport properties of compressible turbulence by replacing the turbulence time scale by a rotation...

Simulation of the Compressible Taylor Green Vortex using High-Order Flux Reconstruction Schemes

In this paper, we investigate the ability of high-order Flux Reconstruction (FR) numerical schemes to perform accurate and stable computations of compressible turbulent flows on coarse meshes. Two new FR schemes, which are optimized for wave dissipation and dispersion properties, are compared to the nodal Discontinuous Galerkin and Spectral Difference methods recovered via the Energy-Stable FR ...

Direct numerical simulation of passive scalar in decaying compressible turbulence

The passive scalars in the decaying compressible turbulence with the initial Reynolds number (defined by Taylor scale and RMS velocity) Re=72, the initial turbulent Mach numbers (defined by RMS velocity and mean sound speed) Mt=0.2-0.9, and the Schmidt numbers of passive scalar Sc=2-10 are numerically simulated by using a 7 order upwind difference scheme and 8 order group velocity control schem...

Gas Kinetic Scheme for DNS of Decaying Compressible Turbulence

We apply the gas-kinetic scheme (GKS) for direct numerical simulation (DNS) of compressible decaying homogeneous isotropic turbulence. We compute dynamics of the kinetic energy K(t), the dissipation rate ε(t), the probability density functions (PDFs) of the twopoint longitudinal velocity difference δu(δr) with a separation distance δr, the shocklet strength χ, and the local Mach number Mat. Our...
