Tracking Particles in Flows near Invariant Manifolds via Balance Functions
Christian Kuehn, Francesco Romano, Hendrik C. Kuhlmann
Particles moving inside a fluid near, and interacting with, invariant manifolds is a common phenomenon in a wide variety of applications. One elementary question is whether we can…

Subcritical versus supercritical transition to turbulence in curved pipes
J. Kühnen, P. Braunshier, M. Schwegel +2
Transition to turbulence in straight pipes occurs in spite of the linear stability of the laminar Hagen--Poiseuille flow if the amplitude of flow perturbations as well as the Reyno…

Experimental investigation of transitional flow in a toroidal pipe
J. Kühnen, M. Holzner, B. Hof +1
The flow instability and further transition to turbulence in a toroidal pipe (torus) with curvature (tube-to-coiling diameter) 0.049 is investigated experimentally. The flow inside…
