A note on forces exerted by a Stokeslet on confining boundaries
Viktor Škultéty, Alexander Morozov
We consider a Stokeslet applied to a viscous fluid next to an infinite, flat wall, or in-between two parallel walls. We calculate the forces exerted by the resulting flow on the co…
Subcritical instabilities in plane Poiseuille flow of an Oldroyd-B fluid
Alexander Morozov, Wim van Saarloos
Recently, detailed experiments on visco-elastic channel flow have provided convincing evidence for a nonlinear instability scenario which we had argued for based on calculations fo…
Geometric scaling of elastic instabilities in the Taylor-Couette geometry: A theoretical, experimental and numerical study
Christof Schaefer, Alexander Morozov, Christian Wagner
We investigate the curvature-dependence of the visco-elastic Taylor-Couette instability. The radius of curvature is changed over almost a decade and the critical Weissenberg number…
Deformation and shape of flexible, microscale helices in viscous flow
Jonathan T. Pham, Alexander Morozov, Alfred J. Crosby +2
We examine experimentally the deformation of flexible, microscale helical ribbons with nanoscale thickness subject to viscous flow in a microfluidic channel. Two aspects of flexibl…
Sudden relaminarisation and lifetimes in forced isotropic turbulence
Moritz Linkmann, Alexander Morozov
We demonstrate an unexpected connection between isotropic turbulence and wall-bounded shear flows. We perform direct numerical simulations of isotropic turbulence forced at large s…
Flagellated bacterial motility in polymer solutions
Vincent A. Martinez, Jana Schwarz-Linek, Mathias Reufer +3
It is widely believed that the swimming speed, , of many flagellated bacteria is a non-monotonic function of the concentration, , of high-molecular-weight linear polymers in…
