Absolute versus convective helical magnetorotational instabilities in Taylor-Couette flows
Rainer Hollerbach, Nigel Sibanda, Eun-jin Kim
We study magnetic Taylor-Couette flow in a system having nondimensional radii and , and periodic in the axial direction with wavelengths . The rotation rati…
Turbulent transport and dynamo in sheared MHD turbulence with a non-uniform magnetic field
Nicolas Leprovost, Eun-Jin Kim
We investigate three-dimensional magnetohydrodynamics turbulence in the presence of both a large-scale velocity and non-uniform magnetic field. By assuming a turbulence driven by a…
Dynamo efficiency with shear in helical turbulence
Nicolas Leprovost, Eun-Jin Kim
To elucidate the influence of shear flow on the generation of magnetic field (the dynamo effect), we study the kinematic limit where the magnetic field does not backreact on the ve…
Statistical theory of structure formation: self-organization
Eun-jin Kim, Han-Li Liu, Johan Anderson
We present the first prediction of the probability distribution function (PDF) for self-organization of shear flows modeled by a nonlinear diffusion equation with a stochastic forc…
Analytical theory of forced rotating sheared turbulence. The Parallel case
Nicolas Leprovost, Eun-Jin Kim
Forced turbulence combined with the effect of rotation and shear flow is studied. In a previous paper [Leprovost and Kim, PRE in press (2008)], we considered the case where the she…
Dynamo quenching due to shear flow
Nicolas Leprovost, Eun-Jin Kim
We provide a theory of dynamo ( effect) and momentum transport in three-dimensional magnetohydrodynamics. For the first time, we show that the effect is severely reduced by…
Analytical theory of forced rotating sheared turbulence. I. Perpendicular case
Nicolas Leprovost, Eun-Jin Kim
We provide a consistent theory of turbulence in the presence of shear and rotation. Starting from a quasi-linear equation for the fluctuating fields, we derive turbulence amplitude…
