FROM LOCALIZED PERIODIC ORBITS TO TRANSIENTS IN PIPE FLOW

Hydrodynamic instability in wall bounded shear flows is abrupt and directly results in very complex spatio-temporal patterns even close to onset. This sudden scenario has challenged the application of dynamical systems concepts to describe the onset of turbulence. We present a bifurcation scenario leading from spatially localized relative periodic orbits to chaotic transients in pipe flow.
