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…
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…
Spectral Modeling of Turbulent Flows and the Role of Helicity
Julien Baerenzung, Helene Politano, Yannick Ponty +1
We present a new version of a dynamical spectral model for Large Eddy Simulation based on the Eddy Damped Quasi Normal Markovian approximation \cite{sao,chollet_lesieur}. Three dis…
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…
