"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.
BRIEF ACADEMIC/EMPLOYMENT HISTORY
MSc in Physics Georgia Tech (1982)
PhD in Physics, Universitaet Bremen (1986)
Postdoc in Juelich, Marburg, San Diego and Rehovot
Professor in Oldenburg 1992-1996
Professor in Marburg since 1996

CURRENT RESEARCH INTERESTS
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
