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…
