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…
An example from turbulence how not to use the invariant function method of Lie-group symmetries
Michael Frewer, George Khujadze
The recent Reply by Oberlack et al. [Phys. Rev. Lett. 130, 069403 (2023)] fails to rebut the critique that a mathematical solution method has been misapplied in their original work…
Refuting the claim of conformal invariance for a zero-vorticity characteristic equation in 2D turbulence
Michael Frewer, George Khujadze
Although the current Reply by Grebenev et al. (2021a) makes their original analysis in Grebenev et al. (2017) more transparent, the actual problem remains. Their claim to have anal…
Aerodynamic sound of turbulent time-developing shear layer as the outcome of the flow linear non-modal instability
George Khujadze, David Gogichaishvili, George Chagelishvili +3
The aim of this paper is to substantiate the importance of non-normality of shear flow linear operators and its consequence -- the non-modal dynamics of the perturbations -- in the…
Conformal invariance and the Lundgren-Monin-Novikov equations for vorticity fields in 2D turbulence: Refuting a recent claim
Michael Frewer, George Khujadze
The recent claim by Grebenev et al. [J. Phys. A: Math. Theor. 50, 435502 (2017)] that the inviscid 2D Lundgren-Monin-Novikov (LMN) equations on a zero vorticity characteristic natu…
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…
