Basin boundary, edge of chaos, and edge state in a two-dimensional model
J. Vollmer, T. M. Schneider, B. Eckhardt
In shear flows like pipe flow and plane Couette flow there is an extended range of parameters where linearly stable laminar flow coexists with a transient turbulent dynamics. When…
Laminar-turbulent boundary in plane Couette flow
Tobias M Schneider, John F Gibson, Maher Lagha +2
We apply the iterated edge state tracking algorithm to study the boundary between laminar and turbulent dynamics in plane Couette flow at Re=400. Perturbations that are not strong…
Lifetime statistics in transitional pipe flow
Tobias M. Schneider, Bruno Eckhardt
Several experimental and numerical studies have shown that turbulent motions in circular pipe flow near transitional Reynolds numbers may not persist forever, but may decay. We stu…
Mixing effectiveness depends on the source-sink structure: Simulation results
Takahide Okabe, Bruno Eckhardt, Jean-Luc Thiffeault +1
The mixing effectiveness, i.e., the enhancement of molecular diffusion, of a flow can be quantified in terms of the suppression of concentration variance of a passive scalar sustai…
