Inertial Range Scaling, Karman-Howarth Theorem and Intermittency for Forced and Decaying Lagrangian Averaged MHD in 2D
J. Pietarila Graham, D. D. Holm, P. Mininni +1
We present an extension of the Karman-Howarth theorem to the Lagrangian averaged magnetohydrodynamic (LAMHD-alpha) equations. The scaling laws resulting as a corollary of this theo…
The imprint of large-scale flows on turbulence
A. Alexakis, P. D. Mininni, A. Pouquet
We investigate the locality of interactions in hydrodynamic turbulence using data from a direct numerical simulation on a grid of 1024^3 points; the flow is forced with the Taylor-…
Low magnetic Prandtl number dynamos with helical forcing
P. D. Mininni, D. C. Montgomery
We present direct numerical simulations of dynamo action in a forced Roberts flow. The behavior of the dynamo is followed as the mechanical Reynolds number is increased, starting f…
Shell to shell energy transfer in MHD, Part II: Kinematic dynamo
Pablo D. Mininni, Alexandros Alexakis, Annick Pouquet
We study the transfer of energy between different scales for forced three-dimensional MHD turbulent flows in the kinematic dynamo regime. Two different forces are examined: a non-h…
Shell to shell energy transfer in MHD, Part I: steady state turbulence
Alexandros Alexakis, Pablo D. Mininni, Annick Pouquet
We investigate the transfer of energy from large scales to small scales in fully developed forced three-dimensional MHD-turbulence by analyzing the results of direct numerical simu…
