Title |
Extracting Order from Disorder: Periodic Orbits Buried in Fluid Turbulence |
|
Abstract |
Ideas from dynamical systems have recently provided fresh insight into transitional and
weakly turbulent flows. Viewing such flows as a trajectory through a phase space littered
with simple invariant ('exact') solutions and their stable and unstable manifolds has
proved a fruitful way of understanding such flows. Central to this approach is identifying
such exact solutions directly from turbulent flow data. I will discuss amongst other things
recent attempts to harness Koopman operator theory in this quest. |
