A spotlike edge state in plane Poiseuille flow

Fluid Dynamics 2015-01-09 v1

Abstract

We study the laminar turbulent boundary in plane Poiseuille flow at Re=1400Re=1400 and 21802180 using the technique of edge tracking. For large computational domains the attracting state in the laminar-turbulent boundary is localized in spanwise and streamwise direction and chaotic.
