Large-scale instabilities in a non-rotating turbulent convection
T. Elperin, I. Golubev, N. Kleeorin +1
Formation of large-scale coherent structures in a turbulent convection via excitation of large-scale instability is studied. The redistribution of the turbulent heat flux due to no…
Energy- and flux-budget (EFB) turbulence closure model for the stably stratified flows. Part I: Steady-state, homogeneous regimes
S. S. Zilitinkevich, T. Elperin, N. Kleeorin +1
We propose a new turbulence closure model based on the budget equations for the key second moments: turbulent kinetic and potential energies: TKE and TPE (comprising the turbulent…
Nonlinear shear-current dynamo and magnetic helicity transport in sheared turbulence
I. Rogachevskii, N. Kleeorin, E. Liverts
The nonlinear mean-field dynamo due to a shear-current effect in a nonhelical homogeneous turbulence with a mean velocity shear is discussed. The transport of magnetic helicity as…
Small-scale magnetic buoyancy and magnetic pumping effects in a turbulent convection
I. Rogachevskii, N. Kleeorin
We determine the nonlinear drift velocities of the mean magnetic field and nonlinear turbulent magnetic diffusion in a turbulent convection. We show that the nonlinear drift veloci…
New mechanism of generation of large-scale magnetic fields in merging protogalactic and protostellar clouds
I. Rogachevskii, N. Kleeorin, A. D. Chernin +1
A new mechanism of generation of large-scale magnetic fields in colliding protogalactic clouds and merging protostellar clouds is discussed. Interaction of the colliding clouds pro…
The distribution of current helicity at the solar surface at the beginning of the solar cycle
D. Sokoloff, S. D. Bao, N. Kleeorin +5
A fraction of solar active regions are observed to have current helicity of a sign that contradicts the polarity law for magnetic helicity; this law corresponds to the well-known H…
