Turbulent transport and coherent structures in 3D plasmas
Keith Leitmeyer
TL;DR
This paper investigates how kinetic and magnetic enstrophy in 3D magnetohydrodynamic plasmas concentrate at smaller scales, improving previous results through a novel ensemble averaging approach.
Contribution
It introduces a new ensemble averaging method to demonstrate enstrophy concentration in 3D MHD, advancing understanding of turbulent plasma behavior.
Findings
Enstrophy concentrates at smaller scales in 3D MHD.
Improved results over previous studies by Bradshaw and Grujić (2013).
Use of redesigned ensemble averages enhances analysis.
Abstract
Kinetic and magnetic enstrophy are shown to concentrate to smaller scales from the integral scale to a Kraichnan-type scale for the 3D magnetohydrodynamic equations. This is an improvement of the result from Bradshaw and Gruji\'c (2013), using redesigned ensemble averages.
