Chaos and irreversibility of a flexible filament in periodically driven Stokes flow

V Agrawal, D Mitra - Physical Review E, 2022 - APS
The flow of Newtonian fluid at low Reynolds number is, in general, regular and time-
reversible due to absence of nonlinear effects. For example, if the fluid is sheared by its …

Tethered flexible polymer under oscillatory linear flow

The non-equilibrium structural and dynamical properties of a flexible polymer tethered to a
reflecting wall and subject to oscillatory linear flow are studied by numerical simulations …

Dynamics of flexible fibers in confined shear flows at finite Reynolds numbers

J Su, K Ma, Z Yan, Q He, X Xu - Physics of Fluids, 2023 - pubs.aip.org
We carry out a numerical study on the dynamics of a single non-Brownian flexible fiber in
two-dimensional confined simple shear (Couette) flows at finite Reynolds numbers. We …
