The generation of spiral density waves by MRI in accretion discs
G. Mamatsashvili, D. Kobaidze, W. Mouhali +2
We investigate the linear dynamics of non-axisymmetric perturbations in Keplerian discs subject to a weak uniform vertical magnetic field in the shearing box approximation. Perturb…
Active modes and dynamical balances in MRI-turbulence of Keplerian disks with a net vertical magnetic field
D. Gogichaishvili, G. Mamatsashvili, W. Horton +1
We studied dynamical balances in magnetorotational instability (MRI) turbulence with a net vertical field in the shearing box model of disks. Analyzing the turbulence dynamics in F…
Dynamics of homogeneous shear turbulence: A key role of the nonlinear transverse cascade in the bypass concept
G. Mamatsashvili, G. Khujadze, G. Chagelishvili +3
To understand the self-sustenance of subcritical turbulence in spectrally stable shear flows, we performed direct numerical simulations of homogeneous shear turbulence for differen…
Nonlinear transverse cascade and two-dimensional magnetohydrodynamic subcritical turbulence in plane shear flows
G. R. Mamatsashvili, D. Z. Gogichaishvili, G. D. Chagelishvili +1
We find and investigate via numerical simulations self-sustained two-dimensional turbulence in a magnetohydrodynamic flow with a maximally simple configuration: plane, noninflectio…
