"Transition to Turbulence in Pipe Flow"


Pipe flow belongs to the group of flows that do not show a linear instability, yet become turbulent for sufficiently high flow speeds. Building on experience in dynamical systems we have proposed a scenario for the transition that involves subcritical bifurcations to unstable travelling waves that form a strange saddle. Numerical and experimental evidence for this scenario will be presented.

Nonlinear dynamics/dynamical systems with few and many degrees of freedom, classical and quantum. I have worked on quantum chaos, periodic orbit theory, fully developed turbulence and transition to turbulence, but fluid dynamics is taking more and more of my time and interests.
