Journal ArticleDOI
The rise of fully turbulent flow
Dwight Barkley,Baofang Song,Baofang Song,Baofang Song,Vasudevan Mukund,Grégoire Lemoult,Marc Avila,Björn Hof +7 more
TL;DR: A bifurcation scenario is uncovered that explains the transformation to fully turbulent pipe flow and the front dynamics of the different states encountered in the process and is bridged between understanding of the onset of turbulence and fully turbulent flows.
Journal ArticleDOI
Destabilizing turbulence in pipe flow
Jakob Kühnen,Baofang Song,Baofang Song,Baofang Song,Davide Scarselli,Nazmi Burak Budanur,Michael Riedl,Ashley P. Willis,Marc Avila,Björn Hof +9 more
TL;DR: In this paper, the authors demonstrate that appropriate distortions to the velocity profile lead to a complete collapse of turbulence and subsequently friction losses are reduced by as much as 90%. But the return to laminar motion is accomplished by initially increasing turbulence intensities or by transiently amplifying wall shear.

Destabilizing turbulence in pipe flow
Jakob Kühnen,Baofang Song,Davide Scarselli,Nazmi Burak Budanur,Ashley P. Willis,Michael Riedl,Marc Avila,Björn Hof +7 more
TL;DR: In this paper, the authors demonstrate that appropriate distortions to the velocity profile lead to a complete collapse of turbulence and subsequently friction losses are reduced by as much as 95% in pipe flow.
Journal ArticleDOI
Nonlinear hydrodynamic instability and turbulence in pulsatile flow.
Duo Xu,Duo Xu,Duo Xu,Atul Varshney,Xingyu Ma,Baofang Song,Michael Riedl,Marc Avila,Björn Hof +8 more
TL;DR: A nonlinear instability mechanism for pulsating pipe flow that gives rise to bursts of turbulence at low flow rates is identified and shows that disordered motion is more common in pulsatile/cardiovascular flows than previous stability considerations suggest.
Journal ArticleDOI
Speed and structure of turbulent fronts in pipe flow
TL;DR: In this article, the physical distinction between the fronts of weak and strong slugs was investigated by analysing the turbulent kinetic energy budget and comparing the downstream front motion to the advection speed of bulk turbulent structures.
