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…

Multiscale Mixing Efficiencies for Steady Sources
Charles R. Doering, Jean-Luc Thiffeault
Multiscale mixing efficiencies for passive scalar advection are defined in terms of the suppression of variance weighted at various length scales. We consider scalars maintained by…
