Hysteresis cycle in a turbulent, spherically bounded MHD dynamo model
We report direct numerical magnetohydrodynamic simulations at low magnetic Prandtl numbers of a turbulent two-cell flow in a bounded, spherical geometry, driven by a constant body force. The flow amplifies infinitesimal magnetic perturbations if the magnetic Reynolds number Rm is larger than a threshold Rmc, resulting in a self-excited equatorial magnetic dipole. However, finite amplitude pertu...
متن کاملA model of nonlinear evolution and saturation of the turbulent MHD dynamo
The growth and saturation of magnetic field in conducting turbulent media with large magnetic Prandtl numbers are investigated. This regime is very common in low-density hot astrophysical plasmas. During the early (kinematic) stage, weak magnetic fluctuations grow exponentially and concentrate at the resistive scale, which lies far below the hydrodynamic viscous scale. The evolution becomes non...
متن کاملTurbulent magnetic pumping in a Babcock-Leighton solar dynamo model
Context. The turbulent pumping effect corresponds to the transport of magnetic flux due to the presence of density and turbulence gradients in convectively unstable layers. In the induction equation it appears as an advective term and for this reason it is expected to be important in the solar and stellar dynamo processes. Aims. In this work, we have explored the effects of the turbulent pumpin...
متن کاملSmall-Scale Turbulent Dynamo
Kinematic dynamo theory is presented here for turbulent conductive fluids. We describe how inhomogeneous magnetic fluctuations are generated below the viscous scale of turbulence where the spatial smoothness of the velocity permits a systematic analysis of the Lagrangian path dynamics. We find analytically the moments and multipoint correlation functions of the magnetic field at small yet finit...
متن کاملThe general relativistic MHD dynamo
The magnetohydrodynamic dynamo equation is derived within general relativity, using the covariant 1+3 approach, for a plasma with finite electric conductivity. This formalism allows for a clear division and interpretation of plasma and gravitational effects, and we have not restricted to a particular spacetime geometry. The results should be of interest in astrophysics and cosmology, and the fo...
