Leveling of MHD turbulence imbalance in shear flows
M. Kavtaradze, G. Mamatsashvili, G. Chagelishvili +1
We investigate magnetohydrodynamic (MHD) turbulence in plane shear flows with a streamwise background magnetic field in the super-Alfvénic regime, i.e., when the flow velocity is l…
Couette flow turbulence reduction by the flow spanwise reflection symmetry breaking: On the universality of the control strategy
George Khujadze, David Gogichaishvili, George Chagelishvili
A novel turbulence control strategy for wall-bounded shear flow is proposed by Chagelishvili et al, 2014. The essence of this strategy involves continuously imposition of specially…
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…
Hydrodynamic stability and mode coupling in Keplerian flows: local strato-rotational analysis
A. G. Tevzadze, G. D. Chagelishvili, J. -P. Zahn
Aims. Qualitative analysis of key (but yet unappreciated) linear phenomena in stratified hydrodynamic Keplerian flows: (i) the occurrence of a vortex mode, as a consequence of stra…
On hydrodynamic shear turbulence in Keplerian disks: via transient growth to bypass transition
G. D. Chagelishvili, J. -P. Zahn, A. G. Tevzadze +1
This paper deals with the problem of hydrodynamic shear turbulence in non-magnetized Keplerian disks. We wish to draw attention to a route to hydrodynamic turbulence which seems to…
