Precision lemmas -- Bibliography -- Back Cover."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 Re, such that sufficiently regular disturbances of size for any exist at least until and in general evolve to be due 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 effect streak growth streak breakdown" scenario for turbulent transition of the 3D Couette flow near the threshold of stability forwarded in the applied mathematics and physics literature"--Provided by publisher.Memoirs of the American Mathematical Society Dynamics Near the Subcritical Transition of the 3D Couette Flow IIViscous flowMathematical modelsStabilityShear flowInviscid flowMixingDamping (Mechanics)Three-dimensional modelingPartial differential equations -- Qualitative properties of solutions -- StabilitymscFluid mechanics -- Hydrodynamic stability -- Parallel shear flowsmscFluid mechanics -- Hydrodynamic stability -- Nonlinear effectsmscFluid mechanics -- Turbulence -- Transition to turbulencemscFluid mechanics -- Turbulence -- Shear flowsmscPartial differential equations -- Qualitative properties of solutions -- Asymptotic behavior of solutionsmscFluid mechanics -- Turbulence -- Turbulent transport, mixingmscViscous flowMathematical models.Stability.Shear flow.Inviscid flow.Mixing.Damping (Mechanics)Three-dimensional modeling.Partial differential equations -- Qualitative properties of solutions -- Stability.Fluid mechanics -- Hydrodynamic stability -- Parallel shear flows.Fluid mechanics -- Hydrodynamic stability -- Nonlinear effects.Fluid mechanics -- Turbulence -- Transition to turbulence.Fluid mechanics -- Turbulence -- Shear flows.Partial differential equations -- Qualitative properties of solutions -- Asymptotic behavior of solutions.Fluid mechanics -- Turbulence -- Turbulent transport, mixing.620.1/064620.106435B3576E0576E3076F0676F1035B4076F25mscBedrossian JacobGermain PierreMasmoudi NaderMiAaPQMiAaPQMiAaPQBOOK9911132646003321UNINA
