Self-consistent mean field MHD
A. Courvoisier, D. W. Hughes, M. R. E. Proctor
We consider the linear stability of two-dimensional nonlinear magnetohydrodynamic basic states to long-wavelength three-dimensional perturbations. Following Hughes & Proctor (2009a…
A novel type of intermittency in a nonlinear dynamo in a compressible flow
Erico L. Rempel, Michael R. E. Proctor, Abraham C. -L. Chian
The transition to intermittent mean--field dynamos is studied using numerical simulations of isotropic magnetohydrodynamic turbulence driven by a helical flow. The low-Prandtl numb…
The Turbulent Magnetic Diffusivity Tensor for Time-Dependent Mean Fields
David W. Hughes, Michael R. E. Proctor
We re-examine the nature of the turbulent magnetic diffusivity tensor of mean field electrodynamics and show that an inconsistency arises if it is calculated via consideration of t…
Double-diffusive instabilities of a shear-generated magnetic layer
Lara J. Silvers, Geoffrey M. Vasil, Nicholas H. Brummell +1
Previous theoretical work has speculated about the existence of double-diffusive magnetic buoyancy instabilities of a dynamically evolving horizontal magnetic layer generated by th…
