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…
