Geometry of transient chaos in streamwise-localized pipe flow turbulence
Nazmi Burak Budanur, Akshunna S. Dogra, Björn Hof
In pipes and channels, the onset of turbulence is initially dominated by localized transients, which lead to sustained turbulence through their collective dynamics. In the present…
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…
