Size-dependent transient nature of localized turbulence in transitional channel flow
Duo Xu, Baofang Song
It has been reported that a fully localized turbulent band in channel flow becomes sustained when the Reynolds number is above a threshold. Here we show evidences that turbulent ba…
Resonances in pulsatile channel flow with an elastic wall
Duo Xu, Matthias Heil, Thomas Seeböck +1
Interactions between fluids and elastic solids are ubiquitous in application ranging from aeronautical and civil engineering to physiological flows. Here we study the pulsatile flo…
Nonlinear hydrodynamic instability and turbulence in pulsatile flow
Duo Xu, Atul Varshney, Xingyu Ma +4
Pulsating flows through tubular geometries are laminar provided that velocities are moderate. This in particular is also believed to apply to cardiovascular flows where inertial fo…
The effect of pulsation frequency on transition in pulsatile pipe flow
Duo Xu, Marc Avila
Pulsatile flows are common in nature and in applications, but their stability and transition to turbulence are still poorly understood. Even in the simple case of pipe flow subject…
Transition to turbulence in pulsating pipe flow
Duo Xu, Sascha Warnecke, Baofang Song +2
Fluid flows in nature and applications are frequently subject to periodic velocity modulations. Surprisingly, even for the generic case of flow through a straight pipe, there is li…
