抄録

We study edge states in the large-domain plane Couette flow. The simple edge state in the minimal Couette flow is sub-harmonically unstable in the large-domain, and we find a steady simple edge state which has broad-streamwise-six waves. It may be expected that this edge state bifurcates into a localized edge state as the length of domain increases.
