This is the second in a pair of works which study small disturbances to the plane, periodic 3D Couette flow in the incompressible Navier-Stokes equations at high Reynolds number Re. In this work, we show that there is constant, independent of, such that sufficiently regular disturbances of sizefor anyexist at least untiland in general evolve to bedue to the lift-up effect. Further, after times, the streamwise dependence of the solution is rapidly diminished by a mixing-enhanced dissipation effect and the solution is attracted back to the class of “2.5 dimensional” streamwise-independent solutions (sometimes referred to as “streaks”). The largest of these streaks are expected to eventually undergo a secondary instability at. Hence, our work strongly suggests, for all (sufficiently regular) initial data, the genericity of the “lift-up effectstreak growthstreak breakdown” scenario for turbulent transition of the 3D Couette flow near the threshold of stability forwarded in the applied mathematics and physics literature.
