On the cross-helicity dependence of the energy spectrum in magnetohydrodynamic turbulence

Journal Article Podesta, J J - Physics of Plasmas

Phenomenological theories of strong incompressible magnetohydrodynamic (MHD) turbulence derived by Goldreich and Sridhar (GS) in 1995 and by Boldyrev in 2006 are only applicable to turbulence with vanishing cross-helicity. In this study, these two theories are generalized to treat turbulence with nonvanishing cross-helicity in such a way that the relation (w{sup +}/w{sup -}){sup 2}=({epsilon}{sup +}/{epsilon}{sup -}){sup 2} observed in numerical simulations is satisfied. The average energy (second order structure function) in the generalized GS theory is E(r{sub perpendicular})={phi}{sub 1}({sigma}{sub c})({epsilon}r{sub perpendicular}){sup 2/3} and that in the generalized Boldyrev theory is E(r{sub perpendicular})={phi}{sub 2}({sigma}{sub c})(v{sub A{epsilon}}r{sub perpendicular}){sup 1/2}, where the functionmore »« less

THE TURBULENT HEATING RATE IN STRONG MAGNETOHYDRODYNAMIC TURBULENCE WITH NONZERO CROSS HELICITY

Journal Article Chandran, Benjamin D. G. ; Hollweg, Joseph V ; Quataert, Eliot ; ... - Astrophysical Journal

Different results for the cascade power {epsilon} in strong, incompressible magnetohydrodynamic turbulence with nonzero cross helicity appear in the literature. In this paper, we discuss the conditions under which these different results are valid. Our conclusions can be expressed in terms of the density {rho}, the rms amplitudes z{sup +} and z{sup -} of Alfvenic fluctuations propagating parallel and antiparallel to the background magnetic field B {sub 0}, and the correlation length (outer scale) measured perpendicular to B {sub 0}, denoted L{sub perpendicular}. We argue that if z{sup +} >> z{sup -} and if the z{sup -} fluctuations are sustainedmore »« less

Strong magnetohydrodynamic turbulence with cross helicity

Journal Article Perez, Jean Carlos ; Boldyrev, Stanislav - Physics of Plasmas

Magnetohydrodynamics (MHD) provides the simplest description of magnetic plasma turbulence in a variety of astrophysical and laboratory systems. MHD turbulence with nonzero cross helicity is often called imbalanced, as it implies that the energies of Alfven fluctuations propagating parallel and antiparallel the background field are not equal. Recent analytical and numerical studies have revealed that at every scale, MHD turbulence consists of regions of positive and negative cross helicity, indicating that such turbulence is inherently locally imbalanced. In this paper, results from high resolution numerical simulations of steady-state incompressible MHD turbulence, with and without cross helicity are presented. It ismore »« less

Scaling and anisotropy in magnetohydrodynamic turbulence in a strong mean magnetic field

Journal Article Grappin, Roland ; LPP, Ecole Polytechnique, 91 Palaiseau ; Mueller, Wolf-Christian - Physical Review. E, Statistical, Nonlinear, and Soft Matter Physics (Print)

We present an analysis of the anisotropic spectral energy distribution in incompressible magnetohydrodynamic turbulence permeated by a strong mean magnetic field. The turbulent flow is generated by high-resolution pseudospectral direct numerical simulations with large-scale isotropic forcing. Examining the radial energy distribution for various angles {theta} with respect to B{sub 0} reveals a specific structure which remains hidden when not taking axial symmetry with respect to B{sub 0} into account. For each direction, starting at the forced large scales, the spectrum first exhibits an amplitude drop around a wave number k{sub 0} which marks the start of a scaling range andmore »« less
