Equilibria are steady states of the Navier-Stokes flow.
As -by definition- they do not move, they cannot be “turbulent.”
Turbulent dynamics is captured by the
(infinity of) unstable periodic solutions, 3D movies that repeat exactly
after some finite time T.
The next three movies show three of the new periodic orbits computed by our group (viewing one will suffice to get the idea):
The first orbits of this type within the S-invariant subspace were computed by Kawahara & Kida, while the first “relative periodic” orbits in the full state-space of plane Couette were computed by Viswanath. |
