A microfluidic band-pass filter for flexible fiber separation
Li Zhibo, Bielinski Clément, Lindner Anke +2
The control of particle trajectories in structured microfluidic environments has significantly advanced sorting technologies, most notably through deterministic lateral displacemen…
Dynamics of rigid fibers interacting with triangular obstacles in microchannel flows
Zhibo Li, Clément Bielinski, Anke Lindner +2
Fiber suspensions flowing in structured media are encountered in many biological and industrial systems. Interactions between fibers and the transporting flow as well as fiber cont…
Dynamics of flexible filaments in oscillatory shear flows
Francesco Bonacci, Brato Chakrabarti, David Saintillan +2
The fluid-structure interactions between flexible fibers and viscous flows play an essential role in various biological phenomena, medical problems, and industrial processes. Of pa…
Fiber buckling in confined viscous flows: an absolute instability described by the Ginzburg-Landau equation
Jean Cappello, Olivia du Roure, François Gallaire +2
We explore the dynamics of a flexible fiber transported by a viscous flow in a Hele-Shaw cell of height comparable to the fiber height. We show that long fibers aligned with the fl…
Signatures of elastoviscous buckling in the dilute rheology of stiff polymers
Brato Chakrabarti, Yanan Liu, Olivia du Roure +2
As a stiff polymer tumbles in shear flow, it experiences compressive viscous forces that can cause it to buckle and undergo a sequence of morphological transitions with increasing…
Flexible filaments buckle into helicoidal shapes in strong compressional flows
Brato Chakrabarti, Yanan Liu, John LaGrone +5
The occurrence of coiled or helical morphologies is common in nature, from plant roots to DNA packaging into viral capsids, as well as in applications such as oil drilling processe…
Morphological transitions of elastic filaments in shear flow
Yanan Liu, Brato Chakrabarti, David Saintillan +2
The morphological dynamics, instabilities and transitions of elastic filaments in viscous flows underlie a wealth of biophysical processes from flagellar propulsion to intracellula…
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…
