Relaminarization of pipe flow by means of 3d-printed shaped honeycombs
Jakob Kühnen, Davide Scarselli, Björn Hof
Based on a novel control scheme, where a steady modification of the streamwise velocity profile leads to complete relaminarization of initially fully turbulent pipe flow, we invest…

Relaminarising pipe flow by wall movement
Davide Scarselli, Jakob Kühnen, Björn Hof
Following the recent observation that turbulent pipe flow can be relaminarised by a relatively simple modification of the mean velocity profile, we here carry out a quantitative ex…

Relaminarization by steady modification of the streamwise velocity profile in a pipe
J. Kühnen, D. Scarselli, M. Schaner +1
We show that a rather simple, steady modification of the streamwise velocity profile in a pipe can lead to a complete collapse of turbulence and the flow fully relaminarizes. Two d…
