Transition to turbulence in pipes and channels
Wednesday, October 29th, 2-3pm, Carslaw 173.
High Reynolds number fluid flows are turbulent in practice, yet
classical linear stability analysis predicts they should be laminar.
This paradox remained largely unresolved for much of the
20th century. This talk will describe the explanation of
subcritical transition to turbulence that emerged in the 1990s,
which owed much to numerical simulations and to fundamental
ideas of numerical linear algebra.
