On the mean field dynamo with Hall effect
Context. MHD turbulence with Hall effect. Aims. Study how Hall effect modifies the quenching process of the electromotive force (e.m.f.) in Mean Field Dynamo (MFD) theories. Methods. We write down the evolution equations for the e.m.f. and for the large and small scale magnetic helicity, treat Hall effect as a perturbation and integrate the resulting equations, assuming boundary conditions such...
متن کاملOn the Connection between Mean Field Dynamo Theory and Flux Tubes
Mean field dynamo theory deals with various mean quantities and does not directly throw any light on the question of existence of flux tubes. We can, however, draw important conclusions about flux tubes in the interior of the Sun by combining additional arguments with the insights gained from solar dynamo solutions. The polar magnetic field of the Sun is of order 10 G, whereas the toroidal magn...
متن کاملSmall-scale magnetic helicity losses from a mean-field dynamo
Using mean-field models with a dynamical quenching formalism, we show that in finite domains magnetic helicity fluxes associated with small-scale magnetic fields are able to alleviate catastrophic quenching. We consider fluxes that result from advection by a mean flow, the turbulent mixing down the gradient of mean small-scale magnetic helicity density or the explicit removal which may be assoc...
متن کاملMixed-parity Solutions in a Mean-field Dynamo Model
S u m m a r y : We consider the effect of including both dipole and quadrupole parities in the previous mean-field model of Hollerbach and Jones (1995), which considered dipole parity only. Allowing for both parities, we find that the onset of dynamo action occurs at a0 « 6, in the form of a purely quadrupolar dynamo wave. A symmetry-breaking bifurcation then occurs at ao « 11, beyond which the...
متن کاملZonal flows in a mean-field solar dynamo model
Cyclic variations are observed in the solar differential rotation profile. The 11 year periodicity of these zonal shear flows (often referred to as “torsional oscillations”) is consistent with the idea that they are driven by the Lorentz forces that are associated with the large-scale solar dynamo. This suggests that these flows may be able to provide indirect observational evidence that can be...
