Triadic energy transfers in non-helical magnetohydrodynamic turbulence

Abstract

The eddy-damped quasi-normal Markovian (EDQNM) two-point statistical closure model is used to study the non-linear triadic energy transfer processes in three-dimensional, incompressible, isotropic, non-helical magnetohydrodynamic (MHD) turbulence in the primitive variable formulation. The triadic transfer functions, which arise from the closure of the three-point correlations in the kinetic energy and magnetic energy spectrum evolution equations, are calculated for non-helical MHD turbulence as a function of wavenumber . An increased degree of non-locality also results in more cancellation between constituent triadic transfer functions.
