Geometry of state space of a turbulent plane Couette flow
Predrag CvitanovicGeorgia Institute of Technology
We propose to use a hierarchy of exact unstable invariant solutions of the Navier-Stokes equations corresponding to the recurrent coherent structures
observed in experiments -- to construct a description of the spatio-temporally chaotic dynamics of turbulent fluid flows as a walk through the space of such structures. This description should allow us to obtain quantitative
predictions of transport properties of fluid flows such as bulk flow rate and mean wall drag.
