Statistical State Dynamics Eigenmodes and Equilibria support Couette Turbulence
Brian F. Farrell, Petros J. Ioannou
Wide-channel Couette (WCC) turbulence consists primarily of quasi-steady roll-streak structures (RSS) maintained by a self-sustaining process (SSP), yet the Navier-Stokes equations…

Statistical state dynamics modes and equilibria underlie the structure and mechanism of wide channel Couette turbulence
Brian F. Farrell, Petros J. Ioannou
Wide channel Couette (WCC) turbulence is striking in being dominated by a large-scale spanwise periodic structure composed of streamwise streaks and associated roll superstructures…
