Kinetic Helicity in the Earth's atmosphere
Otto Chkhetiani, Michael Kurgansky
An overview is given of the helicity of the velocity field (``kinetic'' helicity to distinguish it from the ``magnetic'' helicity used in magnetohydrodynamics, astrophysics, and so…
Four-thirds law of energy and magnetic helicity in electron and Hall magnetohydrodynamic fluids
Yanqing Wang, Otto Chkhetiani
In this paper, by exploiting the feature of the Hall term, we establish some local version four-thirds laws for the dissipation rates of energy and magnetic helicity in both electr…
Helicity Spectra and Dissipation
O. G. Chkhetiani, E. Golbraikh
Both dissipation of helicity and it spectrum we are study on the basis of asymptotic model. Introduction into model dependence of angle between turbulent components vorticity and v…
Influence of helicity on anomalous scaling of a passive scalar advected by the turbulent velocity field with finite correlation time: Two-loop approximation
O. G. Chkhetiani, M. Hnatič, E. Jurcisinova +3
The influence of helicity on the stability of scaling regimes, on the effective diffusivity, and on the anomalous scaling of structure functions of a passive scalar advected by a G…
On triple correlations in isotropic electron magnetohydrodynamic turbulence
Otto Chkhetiani
The evolution of the correlation characteristics in three-dimensional isotropic electron magnetohydrodynamic turbulence is investigated. Universal exact relations between the longi…
Interaction of a rotational motion and an axial flow in small geometries for a Couette-Taylor problem
L. A. Bordag, O. G. Chkhetiani, M. Froehner +1
We analyze the stability of a cylindrical Couette flow under the imposition of a weak axial flow in case of a very short cylinder with a narrow annulus gap. We consider an incompre…
