Problems with kinematic mean field electrodynamics at high magnetic Reynolds numbers
F. Cattaneo, D. W. Hughes
We discuss the applicability of the kinematic -effect formalism at high magnetic Reynolds numbers. In this regime the underlying flow is likely to be a small-scale dynamo, leadi…
Numerical Measurements of the Spectrum in Magnetohydrodynamic Turbulence
Joanne Mason, Fausto Cattaneo, Stanislav Boldyrev
We report the results of an extensive set of direct numerical simulations of forced, incompressible, magnetohydrodynamic turbulence with a strong guide field. The aim is to resolve…
Dynamic Alignment and Exact Scaling Laws in MHD Turbulence
Stanislav Boldyrev, Joanne Mason, Fausto Cattaneo
Magnetohydrodynamic (MHD) turbulence is pervasive in astrophysical systems. Recent high-resolution numerical simulations suggest that the energy spectrum of strong incompressible M…
Dynamic Alignment in Driven Magnetohydrodynamic Turbulence
Joanne Mason, Fausto Cattaneo, Stanislav Boldyrev
Motivated by recent analytic predictions, we report numerical evidence showing that in driven incompressible magnetohydrodynamic turbulence the magnetic- and velocity-field fluctua…
Magnetic-field generation in helical turbulence
Stanislav Boldyrev, Fausto Cattaneo, Robert Rosner
We investigate analytically the amplification of a weak magnetic field in a homogeneous and isotropic turbulent flow lacking reflectional symmetry (helical turbulence). We propose…
On magnetic field generation in Kolmogorov turbulence
Stanislav Boldyrev, Fausto Cattaneo
We analyze the initial, kinematic stage of magnetic field evolution in an isotropic and homogeneous turbulent conducting fluid with a rough velocity field, v(l) ~ l^alpha, alpha<1.…
