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…
