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…
Upper edge of chaos and the energetics of transition in pipe flow
Nazmi Burak Budanur, Elena Marensi, Ashley P. Willis +1
In the past two decades, our understanding of the transition to turbulence in shear flows with linearly stable laminar solutions has greatly improved. Regarding the susceptibility…
Transition to turbulence in particle laden flows
Nishchal Agrawal, George H. Choueiri, Björn Hof
Suspended particles can alter the properties of fluids and in particular also affect the transition from laminar to turbulent flow. In the present experimental study, we investigat…
Dynamics of viscoelastic pipe flow in the maximum drag reduction limit
Jose M. Lopez, George H. Choueiri, Bjoern Hof
Polymer additives can substantially reduce the drag of turbulent flows and the upper limit, the so called "maximum drag reduction" (MDR) asymptote is universal, i.e. independent of…
Complexity of the laminar-turbulent boundary in pipe flow
Nazmi Burak Budanur, Björn Hof
Over the past decade, the edge of chaos has proven to be a fruitful starting point for investigations of shear flows when the laminar base flow is linearly stable. Numerous computa…
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…
