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…
Oscillations of a cantilevered micro beam driven by a viscoelastic flow instability
Anita A. Dey, Yahya Modarres-Sadeghi, Anke Lindner +1
The interaction of flexible structures with viscoelastic flows can result in very rich dynamics. In this paper, we present the results of the interactions between the flow of a vis…
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…
Dynamics of flexible fibers in viscous flows and fluids
O. du Roure, A. Lindner, E. N. Nazockdast +1
The dynamics and deformations of immersed flexible fibers are at the heart of important industrial and biological processes, induce peculiar mechanical and transport properties in…
