The decay of kinetic helicity is studied in numerical models of forced turbulence using either an externally imposed forcing function as an inhomogeneous term in the equations or, alternatively, a term linear in the velocity giving rise to a linear instability. The externally imposed forcing function injects energy at the largest scales, giving rise to a turbulent inertial range with nearly con...
متن کاملEffect of Fractional Kinetic Helicity on Turbulent Magnetic Dynamo Spectra
Magnetic field amplification in astrophysics ultimately requires an understanding of magnetohydrodynamic turbulence. Kinetic helicity has long been known to be important for large scale field growth in forced MHD turbulence, and has been recently demonstrated numerically to be asymptotically consistent with slow mean field dynamo action in a periodic box. Here we show numerically that the magne...
متن کاملMagnetic helicity fluxes in an α dynamo embedded in a halo
We present the results of simulations of forced turbulence in a slab where the mean kinetic helicity has a maximum near the mid-plane, generating gradients of magnetic helicity of both large and small-scale fields. We also study systems that have poorly conducting buffer zones away from the midplane in order to assess the effects of boundaries. The dynamical α quenching phenomenology requires t...
متن کاملAlpha-effect, Helicity and Angular Momentum Transport for a Magnetically Driven Turbulence in the Solar Convection Zone
For a given field of magnetic fluctuations the dynamoas well as the kinetic and current helicities, have been computed, assuming that turbulence is subject to magnetic buoyancy and global rotation. The sign of the dynamois positive in the northern hemisphere and negative in the southern hemisphere. The kinetic helicity has just the same latitudinal distribution as the -effect, indeed there is n...
متن کاملEquatorial magnetic helicity flux in simulations with different gauges
We use direct numerical simulations of forced MHD turbulence with a forcing function that produces two different signs of kinetic helicity in the upper and lower parts of the domain. We show that the mean flux of magnetic helicity from the small-scale field between the two parts of the domain can be described by a Fickian diffusion law with a diffusion coefficient that is approximately independ...
