Outline of Final Research Achievements

In pipe flow the streamwise-localized periodic edge state found by Avila et al. was reproduced by a shooting method. In plane Poiseuille flow the streamwise- and spanwise-localized periodic edge state found by Zammert and Eckhardt was recomputed by a shooting method as well as a Newton-Krylov method. We have succeeded in the theoretical description of a transition route to turbulence through the growth of a turbulent puff or a turbulent spot in terms of the unstable manifold of these spatially localized edge states. We have also discovered a periodic edge state representing a turbulent band in plane Poiseuille flow as well as a steady traveling-wave edge state corresponding to a turbulent puff or a turbulent spot in rectangular-duct flow.
