Non-local interactions in hydrodynamic turbulence at high Reynolds numbers: the slow emergence of scaling laws
P. D. Mininni, A. Alexakis, A. Pouquet
We analyze the data stemming from a forced incompressible hydrodynamic simulation on a grid of 2048^3 regularly spaced points, with a Taylor Reynolds number of Re~1300. The forcing…
Three regularization models of the Navier-Stokes equations
J. Pietarila Graham, Darryl Holm, Pablo Mininni +1
We determine how the differences in the treatment of the subfilter-scale physics affect the properties of the flow for three closely related regularizations of Navier-Stokes. The c…
Rapid directional alignment of velocity and magnetic field in magnetohydrodynamic turbulence
W. H. Matthaeus, A. Pouquet, P. D. Mininni +2
We show that local directional alignment of the velocity and magnetic field fluctuations occurs rapidly in magnetohydrodynamics for a variety of parameters. This is observed both i…
Energy spectra stemming from interactions of Alfven waves and turbulent eddies
P. D. Mininni, A. Pouquet
We present a numerical analysis of an incompressible decaying magnetohydrodynamic turbulence run on a grid of 1536^3 points. The Taylor Reynolds number at the maximum of dissipatio…
Highly turbulent solutions of LANS-alpha and their LES potential
J. Pietarila Graham, Darryl Holm, Pablo Mininni +1
We compute solutions of the Lagrangian-Averaged Navier-Stokes alpha-model (LANS) for significantly higher Reynolds numbers (up to Re 8300) than have previously been accomplished. T…
Adaptive mesh refinement with spectral accuracy for magnetohydrodynamics in two space dimensions
D. Rosenberg, A. Pouquet, P. D. Mininni
We examine the effect of accuracy of high-order spectral element methods, with or without adaptive mesh refinement (AMR), in the context of a classical configuration of magnetic re…
